In the prior art, data is received mainly by using winpe, and then the winpe is restarted, and migration of the system is realized by replacing the winpe with a source end host needing migration. In order to solve the problems, the inventor obtains the technical scheme implemented by the disclosure through creative work.

The main body executing the system migration method according to the embodiment of the present disclosure may be a system migration apparatus, and the system migration apparatus may be a cloud platform as described in the application scenario above.
In some embodiments, the system migration apparatus may also be a third party computer or a third party server. For example, the system migration device is a third-party server, the source host determines partition information of the system disk, and sends the determined partition information of the system disk to the third-party server, and the third-party server obtains the partition information of the system disk of the source host and migrates the system to be migrated to the cloud platform.

The Universal Unique Identifier (UUID) is a standard for software construction. The method aims to ensure that all elements in the distributed system can have unique identification information without specifying the identification information through a central control end. Therefore, in the embodiment of the present disclosure, after the data to be migrated is migrated to the data disk, the universal unique identification code of the data to be migrated in the data disk may be modified, so as to subsequently identify and open the corresponding data information. Also, in some embodiments, the universally unique identification code may be a Globally Unique Identifier (GUID).

GRUB is an implementation of a multi-boot specification that allows a user to have multiple operating systems simultaneously within a computer and select the operating system that he wishes to run at computer boot. GRUB may be used to select different kernels on the operating system partition and may also be used to pass boot parameters to these kernels.

The embodiment of the disclosure provides a new system migration method, which includes: acquiring partition information of a system disk of a system to be migrated in a source host, migrating data to be migrated in the system disk to a data disk of a transfer machine according to the partition information of the system disk, wherein the transfer machine is arranged on a cloud platform, modifying a universal unique identification code of the data to be migrated in the data disk, generating a multi-operating system starting program corresponding to the data to be migrated in the data disk, deploying a virtual machine on the cloud platform according to the data to be migrated in the data disk, so that a user starts the virtual machine based on the modified universal unique identification code and the multi-operating system starting program, migrating the data to be migrated in the system disk to the data disk of the transfer machine according to the partition information of the system disk, so as to realize safe and reliable migration of the data to be migrated, and deploying the virtual machine on the cloud platform according to the data to be migrated in the data disk, the migration of the system of the source end host is completed, the universal unique identification code of the data to be migrated in the data disk is modified, and the multi-operating-system startup program is generated, so that after the deployment of the virtual machine is completed on the cloud platform, namely after the migration of the system of the source end host is completed, a user can start the virtual machine based on the modified universal unique identification code and the multi-operating-system startup program.
It should be noted that, before S101, a step of initialization is further included, such as turning off selinux function in the server, and installing virtio (kvm) driver.
For example, whether selinux of the source host is closed is checked, and if so, the configuration file of selinux is modified. And checking whether a virtio (kvm) driver is installed on the source end host, if not, installing the virtio (kvm) driver on the source end host, if so, checking whether RSYNC software is installed on the source end host, if so, checking whether RSYNC software is also installed on the transfer machine, and if so, starting the RSYNC software on the transfer machine in a daemon mode.
