Detailed Description

In order to enable those skilled in the art to better understand the embodiments of the present application, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In order to clearly illustrate the technical solutions provided by the embodiments of the present application, concepts that may appear in some subsequent embodiments will be first described.

Message queue (Message queue): is a communication mode between processes or between different threads of the same process. The message queue can be used as a container for storing the message in the transmission process, and a process with writing permission on the message queue can add new message into the message queue; a process having read rights to the message queue may then read the message from the message queue. Where the message queue has a first-in first-out principle, i.e. the message that first enters the message queue is read (or sent) first.

The process comprises the following steps: is the basic unit of resource allocation and scheduling by an operating system (such as an android system) regarding one running activity of an application program on a certain data set. Each process occupies an address space, and an application program runs on an operating system in the form of one or more processes to realize corresponding functions.

Thread: is an entity of a process that is a smaller, independently operable basic unit than the process. A thread may share all of the resources owned by a process with other threads that belong to the same process. One thread may create and cancel another thread and multiple threads in the same process may execute concurrently.

Fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present application. As shown in connection with fig. 1, the scenario includes a first electronic device and a second electronic device; the first electronic device may be an old device, and the second electronic device may be a new device. The old device and the new device may be communicatively coupled via a wireless or wired connection. The wired communication connection may be, for example, a universal serial bus (universal serial bus, USB) connection; the wireless connection may be, for example, a wireless fidelity (wireless fidelity, wi-Fi) connection, a bluetooth (bluetooth) connection, a bluetooth mesh connection, a peer-to-peer (P2P) connection, etc. Fig. 1 illustrates an example of a notebook computer as a first electronic device and a second electronic device.

Generally, in order to improve the use experience of a user, the electronic device may respond to the operation of the user to select to migrate all or part of the data stored on the old device to the new device, so as to facilitate the user to continue to use daily important applications, files and the like on the new device. The data stored on the old device may include, for example: video, pictures, documents, APP, and other device configuration. However, in the process of migrating data from the old device to the new device, since each data will be stored in a different storage partition (or hard disk partition) on the new device, when the new device stores the data migrated from the old device, the new device needs to store between the different storage partitions, which results in time consuming process of migrating data from the old device to the new device.

In some embodiments, as shown in FIG. 2, assume that the storage partition of the new device includes a C disk, a D disk, and an E disk; wherein different types of data may be stored in different memory partitions, such as storing operating systems, application programs, or data files. The individual data in the old device may include, for example, data a, data B, data C, and the like. Wherein data a will be stored on the D disk on the new device, data B will be stored on the C disk on the new device, and data C will be stored on the D disk on the new device. On this basis, after the new device receives each data sent by the old device, the new device stores the data according to the storage partition on the old device where the data is to be stored on the new device. For example, the new device stores data a on the D disk, data B on the C disk, and data C on the D disk. In this way, when the new device stores data according to the storage partition of the old device, the new device needs to jump between different storage partitions (such as the C disk and the D disk), that is, the new device stores the data a on the D disk, then stores the data B on the C disk, and then stores the data C on the D disk, so that the process of migrating the data from the old device to the new device is time-consuming, and the user experience is affected.

In some embodiments, the related art may perform data migration in the form of a file when migrating data on an old device to a new device. For example, data a, data B, and data C are data in the same file. On this basis, the data a, the data B and the data C are identical in storage path on the old device (i.e., in the same storage partition of the old device) for the data in the same file. However, the target storage paths of the data a, the data B, and the data C are different, that is, the storage paths of the data a, the data B, and the data C to be stored on the new device are different. In this way, when an old device migrates data to a new device in the form of a file, it may cause a jump between different memory partitions of the new device for data in the same file.

The embodiment of the application provides a data migration method, which can quickly migrate a plurality of first migration data stored on old equipment to new equipment, and improves the efficiency of data migration. Specifically, the old device can sequentially send the first migration data under each target path to the new device according to the storage path (i.e. the target path) of the first migration data on the new device, so that the old device sequentially sends the first migration data to the new device, and the target paths of the first migration data are consistent, and the new device can store the first migration data in the same storage partition according to the first migration data sequentially sent by the old device, thereby improving the efficiency of data migration.

Illustratively, as shown in FIG. 3, data A will be stored on the D-disk on the new device, data B will be stored on the C-disk on the new device, and data C will be stored on the D-disk on the new device. On this basis, the old device sequentially transmits data a and data C to the new device, and then transmits data B again. Thus, the new device may first store data A and data C on the D-disk, and then store data B on the C-disk.

The data migration method provided by the embodiment of the application can be applied to the communication system described in fig. 1. The first electronic device and the second electronic device shown in the communication system may be, for example, one of a notebook computer, a tablet computer, a large-screen display device, a desktop, a laptop, a handheld computer, a vehicle-mounted device, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR) \virtual reality (VR) device, and the like, and the specific form of the electronic device is not particularly limited in the embodiments of the present application.

The GPU is a microprocessor for image processing, and is connected to the display 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

The display screen 194 is used to display images, videos, and the like. The display 194 includes a display panel. The display panel may employ a liquid crystal display (liquid crystal display, LCD), an organic light-emitting diode (OLED), an active-matrix organic light emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Mini-LED, a Micro-OLED, a quantum dot light-emitting diode (quantum dot light emitting diodes, QLED), or the like.

The electronic device 100 may implement photographing functions through an ISP, a camera 193, a video codec, a GPU, a display screen 194, an application processor, and the like.

The ISP is used to process data fed back by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing and is converted into an image visible to naked eyes. ISP can also optimize the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image onto the photosensitive element. The photosensitive element may be a charge coupled device (charge coupled device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format. In some embodiments, the electronic device may include 1 or N cameras 193, N being a positive integer greater than 1.

The external memory interface 120 may be used to connect an external memory card, such as a Micro SD card, to enable expansion of the memory capabilities of the electronic device. The external memory card communicates with the processor 110 through an external memory interface 120 to implement data storage functions. For example, audio, video, etc. files are stored in an external memory card.

It is to be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device may include more or less components than illustrated, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of hardware and software.

The following describes a specific implementation procedure of the data migration method provided in the embodiment of the present application with reference to the accompanying drawings.

In the embodiment of the application, the old device and the new device can perform data migration through a data migration application or an application with a data migration function. It should be appreciated that prior to the old device and the new device performing data migration, the old device and the new device first establish a communication connection, and then the old device and the new device initiate a data migration function to perform data migration.

Taking the old device and the new device with data migration applications installed thereon as an example for illustration, in some embodiments, the old device and the new device automatically launch the data migration applications to launch the data migration functions when the old device and the new device are powered on. In other embodiments, the home page of the computer manager application of the old device and the new device includes a data migration setting item, and the old device and the new device may initiate a data migration function in response to a user operating the data migration setting item. In still other embodiments, a data migration application is installed on desktops of the old device and the new device, and the old device and the new device may initiate data migration functions in response to user operations on the data migration application.

Taking the example where the home page of the computer manager application of the old device and the new device includes a data migration setting item as an illustration, the old device and the new device display an interface 201 as shown in (1) of fig. 5 in response to a user's operation of the data migration setting item, the interface 201 including a start control. Wherein the launch control may be, for example, "immediate migration". The old device and the new device then display an interface 202 as shown in fig. 5 (2) in response to the user's operation of the launch control, the interface 202 including first prompting information for prompting the user for data migration user protocols. For example, the first prompt information may be: the service needs to turn on WLAN and Bluetooth, and occupies WLAN channels in the migration process, so that the network cannot be accessed temporarily, the service can automatically recover after the migration is completed, and 'consent' is clicked, namely, consent to the content and data migration user protocol is indicated.

Still as with interface 202 shown in fig. 5 (2), in some embodiments, the interface 202 further includes an consent control and a cancel control, the old device and the new device opening a data migration function in response to a user operation of the consent control; the old device and the new device exit the data migration in response to a user operation to cancel the control.

When the old device and the new device respond to the user's operation of the consent control, the old device and the new device display an interface 203 as shown in (3) of fig. 5, the interface 203 including a first icon and a second icon; wherein the first icon is used to indicate a new device and the second icon is used to indicate an old device. Illustratively, the old device responds to the operation of the user on the second icon, and selects the old device as the local device to serve as a data sender; and the new device responds to the operation of the user on the first icon, and selects the local device as the new device to serve as a data receiving party.

Also shown as interface 203 in fig. 5 (3), in some embodiments, the interface 203 further includes a second hint information that is used to hint the installation path of the data migration application to the user. The second prompt information may be, for example: please go to official website: http:// www.xxx.com downloads the install data migration application. In some embodiments, interface 203 further includes an exit control, which the old device and the new device exit data migration functionality in response to user operation of the exit control.

In some embodiments, the old device displays an interface 204 as shown in fig. 6 (1) in response to a user operation of the second icon; the interface 204 is the interface where the old device waits to be discovered. Illustratively, the old device sends a broadcast to the new device, and the "old device" in the display interface 204 is waiting for a reminder to be found. In some embodiments, interface 204 also includes a third hint information that is used to hint to the user to launch the data migration application on the new device. The third prompt information may be, for example: a data migration application is launched on the new device, selecting "this is the new device". If the new device does not install the data migration application, please go to the official website: http:// www.xxx.com downloads the install data migration application. In some embodiments, interface 204 also includes a prompt for "WLAN channel is occupied during migration, device cannot use network". In other embodiments, interface 204 also includes a "cancel" control; on this basis, the old device exits the data migration in response to a user operation of the "cancel" control.

In other embodiments, the new device displays an interface 205 as shown in fig. 6 (2) in response to a user operation of the first icon; the interface 205 is the interface where the new device is looking for the old device. Illustratively, the new device receives the broadcast sent by the old device and displays a prompt in interface 205 that device … is being looked up. In some embodiments, interface 205 also includes fourth hints information for prompting the user to launch a data migration application on the old device. The fourth prompt information may be, for example: a data migration application is launched on the old device, selecting "this is the old device". If the old device does not install the data migration application, please go to the official website: http:// www.xxx.com downloads the install data migration application. In some embodiments, interface 205 also includes a "continue" control and a "cancel" control. It should be noted that when the new device does not find the old device, the "continue" control is not clickable. If the user clicks the cancel control, the new device responds to the operation of the cancel control by the user, and the new device exits from data migration.

In some embodiments, after the new device finds the old device, the new device responds to the user's operation of the "continue" control in interface 205, the old device and the new device display a connection authentication interface, and if the connection authentication passes, the old device and the new device establish a communication connection. On this basis, the old device and the new device can perform data migration.

Illustratively, the old device and the new device may perform connection authentication by checking the connection code. For example, in response to operation of the "continue" control in user interface 205, the new device displays interface 206 as shown in FIG. 7 (1), which interface 206 includes a connection check code. The connection check code may be, for example, "078913". In some embodiments, interface 206 also includes a prompt such as "please see if the following connection code is displayed on the old device". In other embodiments, the interface 206 also includes a "cancel" control, e.g., the new device exits the data migration in response to a user's operation of the "cancel" control.

Accordingly, the old device displays an interface 207 as shown in fig. 7 (2), the interface 207 including a connection check code. The connection check code may be, for example, "078913". In some embodiments, interface 207 also includes a prompt such as "find that a new device is requesting a connection to the local, please confirm whether the following connections are consistent. In other embodiments, interface 207 also includes a "continue" control and a "cancel" control; under the condition that the connection check code on the old equipment is consistent with the connection check code on the new equipment, if the old equipment responds to the operation of the 'continue' control by the user, the old equipment and the new equipment are in communication connection; if the old device responds to the user operation of the "cancel" control, the old device exits the data migration.

Illustratively, in response to a user's operation of the "continue" control, the old device and the new device display an interface 208 as shown in FIG. 8, the interface 208 being the interface to which the old device and the new device are being connected. For example, as shown in FIG. 8, the interface 208 may include, for example, a prompt for "in connection" and a "cancel" control. In some embodiments, the old or new device exits the data migration in response to a user operation of a "cancel" control.

In connection with the above-described embodiments and the interfaces shown in fig. 5-8, data migration between the old device and the new device may begin after the old device establishes a communication connection with the new device. The process of data migration between the old device and the new device may be implemented, for example, in conjunction with the flow diagram shown in fig. 9 and the method described in the embodiments below. Specifically, as shown in fig. 9, the process of the data migration method may include S301 to S305.

S301, the old device sends migration information I to the new device.

The first migration information comprises a data identifier of each first migration data in the N first migration data and a storage path of the first migration data on the old equipment, wherein the storage path is indicated by the data identifier; n is a positive integer. In the embodiment of the present application, the first migration information may also be referred to as second migration information.

Wherein the data identification refers to a unique identification code capable of characterizing the first migration data. By way of example, the data identification may be, for example, a file name of the first migration data.

It should be noted that, the N pieces of first migration data may be stored on the old device in the form of pictures, videos, and documents, for example. In some embodiments, a portion of at least one first migration data of the N first migration data is stored under a first storage path of the old device, and another portion is stored under a second storage path of the old device, i.e., at least one first migration data is stored under a different storage path of the old device. Illustratively, the N first migration data includes data a, a portion of which is stored on the old device along a path C: and the storage path of the other part on the old equipment is D/AAA/t.txt. Wherein the storage path of the first migration data on the old device may also be referred to as the source path of the first migration data.

Illustratively, suppose that the N first migration data includes data a, data b, and data c, where migration information sent by the old device to the new device is shown in table 1 below.

TABLE 1

In other embodiments, at least two of the N first migration data are data within the same file. Illustratively, data a, data b, and data c may be data within the same file; thus, the storage paths for data a, data b, and data c on the old device are the same, but the target paths on the new device may not be the same.

In some embodiments, the old device displays interface 209 as shown in FIG. 10 while the old device sends migration information one to the new device; the interface 209 includes a progress bar for the old device to send migration information one to the new device, as well as a "cancel" control. Meanwhile, a prompt interface for successful connection is displayed on a display screen of the new equipment. The progress bar is used for prompting a user of the progress of the old equipment for sending migration information I to the new equipment.

In some embodiments, the old device exits the data migration in response to a user operation of a "cancel" control.

S302, the new device determines a target path identifier of each first migration data in M first migration data according to a preset disk storage rule according to first migration information.

The preset storage rule is used for indicating a corresponding relation between a storage path of the first migration data on the old device and a path identifier (such as path type) of a storage path corresponding to the first migration data to be stored in the new device. In addition, the target path identification is used to indicate a storage path in which the corresponding first migration data is to be stored in the new device. M is a positive integer, M is less than or equal to N.

In the embodiment of the application, the storage path where the first migration data is to be stored in the new device may also be referred to as a target path. In addition, in this embodiment, m=n.

Illustratively, assume that the M first migration data includes data a, data b, and data c; on this basis, the preset inventory rules are shown in table 2 below.

First migration data	Data identification	Source Path	Target path	Target path identification
					Data a	a1	C:\\AAA\t.txt	C:\\AAA\t.txt	1
	a2	D:\\AAA\t.txt	E:\\BBB\t.txt	3
					Data b	b	E:\\BBB\t.txt	F:\\AAA\t.txt	4
Data c	c	F:\\111\t.txt	C:\\AAA\t.txt	1

TABLE 2

It should be noted that the path identifier relates to a storage partition (or hard disk partition) on the new device. Exemplary, for example, storage partitions on new devices include C: \i.e., C disk, D: \i.e., D disk, E: \i.e., E disk, F: \i.e., F disk; the corresponding path identifications may be, for example, C: \1, D: \2, E: \3, F: \4.

For example, referring to table 2, for example, the target path corresponding to the data identifier a1 is C: AAA t.txt, that is, the data a indicated by the data identifier a1 is to be stored on the C disk of the new device, then the path identifier of the target path corresponding to the data identifier a1 is 1. Accordingly, the target path corresponding to the data identifier a2 is E: if the data a indicated by the data identifier a2 is to be stored on the E-disk of the new device, the path identifier of the target path corresponding to the data identifier a2 is 3. Correspondingly, the target path corresponding to the data identifier b is F: AAA t.txt, that is, the F disc to which the data b indicated by the data identifier b is to be stored on the new device, then the path identifier of the target path corresponding to the data identifier b is 4. Correspondingly, the target path corresponding to the data identifier C is C: AAA t.txt, i.e. the D disc where the data indicated by the data identifier b is to be stored on the new device, then the path identifier of the target path corresponding to the data identifier C is 2.

In some embodiments, a child partition is also included in the different memory partition. Taking the storage partition on the new device as C: \ (i.e., a C disk) as an example, the C disk may include, for example: c \AAA\, C \BBB\, C \DDD\and the like. Based on this, in order to further increase the efficiency of data migration, in some embodiments, path identifiers may be set according to the sub-partitions included in different storage partitions, i.e., the path identifiers correspond to the sub-partitions included in the storage partition on the new device.

Taking M first migration data as an example, the M first migration data includes data d, data e, and data f; on this basis, the preset inventory rules are shown in table 3 below.

First migration data	Data identification	Source Path	Target path	Target path identification
					Data d	d	C:\\AAA\t.txt	C:\\AAA\t.txt	1’
Data e	e	E:\\BBB\t.txt	C:\\BBB\t.txt	1”
					Data f	f	F:\\111\t.txt	D:\\AAA\t.txt	2’

TABLE 3 Table 3

For example, referring to table 3, for example, the target path corresponding to the data identifier d is C: AAA t.txt, that is, the data d indicated by the data identifier d will be stored in the sub-partition C: \AAA\ in the C disk on the new device, then the path identifier of the target path corresponding to the data identifier d is 1'. Correspondingly, the target path corresponding to the data identifier e is C: and (3) BBB t.txt, namely, the data e indicated by the data identifier e is to be stored in the sub-partition C in the C disk on the new device, wherein the path identifier of the target path corresponding to the data identifier e is 1". Correspondingly, the target path corresponding to the data identifier f is D: AAA t.txt, that is, the sub-partition D in D disk indicated by data identifier f will be stored in new device AAA, then the path identifier of the target path corresponding to data identifier f is 2'.

And S303, the new equipment sends migration information II to the old equipment.

The migration information II comprises: a data identifier of each first migration data in the M first migration data, and a target path identifier of the first migration data indicated by the data identifier. In the embodiment of the present application, the second migration information may also be referred to as first migration information.

Illustratively, assume that the M first migration data includes data a, data b, and data c, where migration information sent by the new device to the old device is shown in table 4 below.

First migration data	Data identification	Target path identification
			Data a	a1	1
	a2	3
			Data b	b	4
Data c	c	1

TABLE 4 Table 4

S304, the old equipment sequentially sends first migration data corresponding to each target path identifier to the new equipment according to the target path identifiers of the first migration data in the M pieces of first migration data.

In some embodiments, at least two first migration data of the M first migration data are data within the same file. On this basis, the storage paths of the at least two first migration data on the old device are identical, but the target paths of the at least two first migration data on the new device may be different.

Illustratively, in combination with the above table 4, the migration information two sent by the new device is received by the old device, where the migration information two includes the data identifier and the target path identifier of the data a, the data identifier and the target path identifier of the data b, and the data identifier and the target path identifier of the data c. On the basis, the old equipment sequentially sends first migration data corresponding to each target path identifier to the new equipment according to the target path identifiers of the data a, the data b and the data c.

For example, the old device transmits a part of data a and data c corresponding to the target path identifier 1 to the new device, then transmits another part of data a corresponding to the target path identifier 3, and finally transmits data b corresponding to the target path identifier 4. It should be understood that each target path identifier corresponds to at least one first migration data of the M first migration data.

In this way, the target path identifiers of the first migration data sent by the old device to the new device in turn are consistent, i.e. the target paths of the first migration data stored on the new device by the old device to the new device in turn are consistent, so that the new device can store the first migration data in the same storage partition of the new device according to the target path identifiers of the first migration data, thereby improving the efficiency of data migration.

In addition, when at least two first migration data are data in the same file and the target paths of the at least two first migration data are different, the old equipment also sends the first migration data corresponding to each target path identifier to the new equipment, namely, the data in the same file are separately sent, so that the efficiency of data migration is further improved.

S305, the new device stores the received first migration data in the new device according to the target path identification of the received first migration data.

The new device stores the received first migration data in the target path corresponding to the target path identifier. For example, referring to Table 2, the target path corresponding to target path identification 1 includes C: \AAA\t.txt, so that the new device may store the first migration data (e.g., a portion of the data in data a) indicated by target path identification 1 under target path C: \AAA\t.txt. As also shown in table 2, the target path corresponding to the target path identifier 1 further includes C: AAA t.txt such that the new device may store the first migration data (e.g., data C) indicated by target path identification 1 in target path C: AAA t.txt.

In this way, the new device can store the first migration data corresponding to the same target path identifier in one storage partition according to the target path identifier of the received first migration data, and then store the first migration data corresponding to the other target path identifier in the other storage partition, thereby solving the problem that the new device needs to jump between different storage partitions when storing the migration data sent by the old device, and improving the efficiency of data migration.

In some embodiments, as shown in fig. 11 in conjunction with fig. 9, after S301, that is, after the old device sends migration information one to the new device, the data migration method further includes:

s3011, the new device displays the first interface.

The first interface is used for selecting one or more first migration data from the N first migration data.

Illustratively, as shown in FIG. 12, after the new device receives migration information one sent by the old device, the new device displays an interface 210 (i.e., a first interface); the interface 210 includes the name of the storage partition of the old device and a data identification (e.g., file name) of the N first migration data stored under the storage partition of the old device. In some embodiments, the interface 210 further includes hints for the storage space size of the new device, hints for the file size of the selected first migration data, hints for the number of selected first migration data, hints for the expected migration duration, and the like. In some embodiments, interface 210 also includes a "begin migration" control and a "cancel" control.

S3012, the new device determines M pieces of first migration data according to a selection operation of a user on M pieces of first migration data in N pieces of first migration data on a first interface.

Illustratively, as shown in FIG. 12, interface 210 includes a "local disk C" selection and a "local disk D" selection; wherein, the selection items of the local disk D comprise a My file selection item and a My Drive selection item; the My File sub-selections include "index" and "image" files. For example, the new device responds to a selection operation of the user selection item "local disk C" in the interface 210, and "local disk C" is selected. Accordingly, the new device may also select M first migration data from the N first migration data in response to a user selection operation of other options in the interface 210.

In some embodiments, as shown in fig. 13 in conjunction with fig. 11, after S302, that is, after the new device determines, according to the migration information one, the target path identifier of each first migration data in M first migration data according to the preset inventory rule, the data migration method further includes:

s3021, the new device sorts the target path identifiers of each first migration data in the M first migration data according to a preset sequence.

Wherein the target path identifiers of the same kind are arranged together.

In some embodiments, the preset order may be, for example, a small to large order; or may be in order from large to small.

Illustratively, as shown in connection with Table 4 above, the target path identification includes: target path identification 1, target path identification 3, target path identification 4, and target path identification 1. Taking the order of the preset order from small to large as an example, the new device orders the target path identifiers of each first migration data in the M first migration data according to the preset order, and then the order of the target path identifiers is the target path identifier 1, the target path identifier 3 and the target path identifier 4.

On the basis, in the migration information II sent by the new equipment to the old equipment, the target path identifiers are arranged according to the preset sequence, so that the old equipment can send first migration data corresponding to the same target path identifier to the new equipment according to the arranged sequence of the target path identifiers, and the data migration efficiency can be further improved.

In some embodiments, the target path identification of the M first migration data includes: a first identifier and a second identifier; as shown in fig. 14, according to the target path identifier of each first migration data in the M first migration data, the old device sequentially sends first migration data corresponding to each target path identifier to the new device, including:

S3041, the old equipment sends first migration data corresponding to the first identification to the new equipment.

S3042, after the old equipment sends the first migration data corresponding to the first identifier, the old equipment sends the first migration data corresponding to the second identifier to the new equipment.

For example, as shown in the above table 4, assuming that the first identifier is the target path identifier 1 and the second identifier is the target path identifier 2, on the basis of this, the old device selects the first migration data corresponding to the target path identifier 1 according to the target path identifiers of the M first migration data, and sends the first migration data corresponding to the target path identifier 1 to the new device. And then, the old equipment selects the second migration data corresponding to the target path identifier 2 and sends the first migration data corresponding to the target path identifier 2 to the new equipment.

In this way, the old device can ensure that the first migration data sequentially sent to the new device is the first migration data corresponding to the same target path identifier, so that the new device can store the first migration data corresponding to the same target path identifier first, and the data migration efficiency is improved.

Illustratively, the first identifier corresponds to a plurality of first migration data; on this basis, the old device can run a plurality of threads and respectively send a plurality of first migration data corresponding to the first identifier to the new device.

For example, as shown in FIG. 15, the old device runs thread A, thread B, and thread C; the old equipment operating thread A acquires first migration data corresponding to the first identifier, the operating thread B acquires first migration data corresponding to the first identifier, and the operating thread C acquires first migration data corresponding to the first identifier. And then, the old equipment simultaneously runs the thread A, the thread B and the thread C and sends first migration data corresponding to the first identifier to the new equipment.

Correspondingly, the second identifier corresponds to a plurality of first threads; on this basis, the old device can run a plurality of threads and respectively send a plurality of first migration data corresponding to the second identifier to the new device.

In this way, the old device can concurrently execute the first migration data corresponding to the first identifier sent to the new device by running a plurality of threads, thereby improving the resource utilization rate and further improving the data migration efficiency.

In other embodiments, the target path identification of the M first migration data includes: a first identifier and a second identifier; as shown in fig. 16, according to the target path identifier of each first migration data in the M first migration data, the old device sequentially sends first migration data corresponding to each target path identifier to the new device, including:

S304a, after the old equipment sequentially adds the data identifiers of all the first migration data corresponding to the first identifiers into the data queue to be migrated, sequentially adds the data identifiers of all the first migration data corresponding to the second identifiers into the data queue to be migrated.

It should be noted that, the explanation of the data queue to be migrated may refer to the explanation of the message queue in the above embodiment, which is not described herein.

And S304b, the old equipment sends the first migration data in the data queue to be migrated to the new equipment according to the first-in first-out principle.

The data identifiers of all the first migration data corresponding to the first identifiers are assumed to comprise: a1, a2, a3, b1, and b2; the data identifier of the first migration data corresponding to the second identifier comprises: b3, b4, c1, etc. For example, as shown in fig. 17, after the old device adds the data identifiers a1, a2, a3, b1 and b2 of the first migration data corresponding to the first identifier to the data queue to be migrated, the old device adds the data identifiers b3, b4 and c1 of the first migration data corresponding to the second identifier to the data queue to be migrated.

It should be appreciated that the data queue to be migrated has a first-in first-out principle, i.e., data that enters the queue first-out. In other words, the old device transmits data (data indicated by the data identifier a 1) that first entered the data queue to be migrated to the new device, and after the data indicated by the data identifier a1 is transmitted, the old device continues to transmit the data (data indicated by the data identifier a 2) of the data queue to be migrated to the new device. It should be noted that, every time the old device sends data of a data queue to be migrated to the new device, the data queue to be migrated will be added with a new data identifier.

It should be noted that the target path identifier may further include a third identifier, a fourth identifier, and the like. On the basis, after the old equipment adds the data identifiers of all the first migration data corresponding to the second identifier into the data queue to be migrated, the old equipment adds the data identifiers of all the first migration data corresponding to the third identifier into the data queue to be migrated. Correspondingly, after the old equipment adds the data identifiers of all the first migration data corresponding to the third identifier into the data queue to be migrated, the old equipment adds the data identifiers of all the first migration data corresponding to the fourth identifier into the data queue to be migrated.

In some embodiments, after the old device adds all the first migration data corresponding to the first identifier to the data queue to be migrated, the old device runs a plurality of threads and sends the first migration data corresponding to the first identifier to the new device in parallel. In this way, the old equipment runs a plurality of threads to send the first migration data corresponding to the first identifier to the new equipment in parallel, and the data migration efficiency is further improved.

For example, as shown in fig. 18, the step of the old device sequentially adding the data identifiers of all the first migration data corresponding to the first identifier to the to-be-migrated data queue includes:

S401, the old equipment acquires the target data identification.

The target data identifier is a data identifier corresponding to one of M pieces of first migration data.

S402, the old equipment judges whether the target data identifier is a data identifier corresponding to the last migration data in the M first migration data.

If the target data identifier is not the data identifier corresponding to the last migration data in the M first migration data, the old device executes S403; if the target migration data is the data identifier corresponding to the last migration data in the M first migration data, the old device executes S405.

It should be noted that, the data identifier corresponding to the last migration data refers to the data identifier corresponding to the last data in all the first migration data that is not processed (i.e. does not perform the step shown in fig. 18) by the old device in the M first migration data.

S403, the old equipment judges whether the target path identifier of the first migration data indicated by the target data identifier is identical to the preset path identifier.

The preset path identifier is an object path identifier corresponding to the first migration data in the M first migration data.

If the target path identifier of the first migration data indicated by the target data identifier is the same as the preset path identifier, the old device adds the target data identifier to the data list, and executes S404; if the target path identifier of the first migration data indicated by the target data identifier is different from the preset path identifier, the old device adds the data identifier of the first migration data included in the data list into the data queue to be migrated, updates the preset path identifier, and re-executes S401-S404.

S404, the old device judges whether the number of the data identifications included in the data list is greater than or equal to a threshold value.

If the number of the data identifiers included in the data list is greater than or equal to a threshold value, the old equipment adds the data identifiers included in the data list into a data queue to be migrated; if the number of data identifications included in the data list is smaller than the threshold value, the old device re-executes S401-S404.

In this embodiment, when the old device determines that the number of the data identifiers included in the data list is greater than or equal to the threshold, the old device adds the data identifiers included in the data list to the data queue to be migrated, so that resources of the data queue to be migrated can be effectively utilized, and efficiency of data migration is improved.

And S405, the old equipment adds the data identification included in the data list into a data queue to be migrated.

In some embodiments, after the old device adds the data identifier included in the data list to the data queue to be migrated, the old device empties the data list so that the old device stores the data identifier of the first migration data corresponding to the next target path identifier in the data list.

In summary, it can be seen that the old device can add the data identifier of the first migration data corresponding to the target path identifier of the same kind into the data queue to be migrated by judging the target path identifier corresponding to the first migration data indicated by the target data identifier and the preset path identifier; in this way, the old device can send the first migration data to the new device according to the data identification in the data queue to be migrated, so that the target path identifications of the first migration data which are sequentially sent to the new device are all the same, and the data migration efficiency is improved.

In some embodiments, as shown in connection with FIG. 12, the old device and the new device begin data migration in response to a user operation of an "open migration" control in the first interface. Illustratively, the old device and the new device display an interface 211 as shown in FIG. 19; the interface 211 includes prompt information for prompting the user for data migration progress. For example, interface 211 includes migration progress (e.g.,%), size of migrated data, migration rate, and remaining time, etc.

In some embodiments, when the old device migrates all of the M first migration data onto the new device, the old device and the new device display an interface 212 as shown in fig. 20; the interface 212 is an interface where the old device and the new device complete data migration. Illustratively, the interface 212 includes prompt information for prompting the user that the migration is complete, a migration duration, a size of the migration data, a number of files of the migration data, and the like. In other embodiments, interface 212 also includes a "complete" control. For example, the old device exits the data migration in response to a user operation of the "done" control; accordingly, the new device exits the data migration in response to user operation of the "done" control.
