8. A data migration method using the computer data migration apparatus according to any one of claims 1 to 7, characterized in that: the data migration method comprises the following steps:
(1) equipment connection: preparing a computer data migration device and a source computer and a target computer to be subjected to data migration, ensuring that the source computer and the target computer are not connected with a USB storage device, and respectively connecting the source computer and the target computer with the computer data migration device through a first USB line and a second USB line;
(2) connection pairing: before data migration begins, setting a source computer and a target computer to be started through a BIOS (basic input/output System) as a USB (Universal Serial bus) flash disk, restarting the source computer and the target computer, starting a source computer end migration program on a memory A and a target computer end migration program on a memory B along with the starting of the source computer end migration program and the target computer end migration program, displaying a random connection code and a connection password on data migration interfaces of the source computer and the target computer in a waiting pairing state, and binding fixed ports of the two migration programs through a TCP (Transmission control protocol) protocol to wait for connection; then inputting a connection code and a connection password of another computer into a data migration interface of the source computer or the target computer, pairing migration programs on the two computers, establishing a stable connection channel between the source computer and the target computer through a TCP (transmission control protocol) after pairing is successful, and automatically closing a pairing state;
(3) device mode determination: after the pairing of the two migration programs is completed, the migration programs on the two computers enter an equipment mode determining stage, and options determined by the equipment mode are displayed on data migration interfaces of the two computers; the migration program of the source computer end and the migration program of the target computer end have two working modes, namely a source computer mode and a target computer mode, wherein the migration program on the source computer should select the source computer mode, and the migration program on the target computer should select the target computer mode; when one computer makes a mode selection, the TCP channel established in the step (2) is used for informing the other computer, and the other computer automatically works in the other mode;
(4) data migration: after the working modes of the two migration programs are determined, a data migration stage is entered, at this time, a target computer side migration program working in a target computer mode enters a waiting state, a source computer side migration program working in a source computer mode enters a file selection state, a user selects and confirms a file to be migrated on a source computer, and then sends a migration instruction through a TCP channel established in the step (2), the migration program of the source computer side automatically generates a migration list according to a data item selected by the user and sends the migration list to the migration program of the target computer side, the migration program of the target computer side analyzes the list file and stores the list file in a temporary folder for data comparison in the data migration process and the later period after receiving the list migration, and then a data migration interface on the target computer pops up a dialog box for selecting the storage position of the file, after the storage position is selected, clicking a confirmation button to start entering a data migration state, in the data migration process, verifying the integrity of each piece of data by a migration program, retransmitting files with errors in migration, and entering the next stage after all files are migrated;
(5) data verification and report export: and after the data migration is finished, comparing and verifying the data by the migration program at the target computer end, retransmitting the missing and error-compared data, and after the transmission is finished, exporting a migration report by the migration program at the target computer end to finish the data migration.
9. The computer data migration method according to claim 8, wherein: the migration list comprises a to-be-migrated data list, a file name and an md5 value corresponding to each piece of data and the size of the data; and in the data migration process, the file with the migration error is retransmitted, and the retransmission is abandoned after three transmission attempts fail.
10. The computer data migration method according to claim 8, wherein: after the data migration is completed, the migration program at the target computer terminal compares and verifies the migrated data according to the file list on the migration list received before the data transmission and the md5 value of each file; the migration report comprises statistical information including a list of files which are successfully migrated, a list of files which are unsuccessfully migrated, and the amount of data migrated.
