What Is Server Migration Service

Server Migration Service (SMS) provides P2V and V2V migration services to help you migrate applications and data from on-premises x86 physical servers or VMs on private or public clouds to HUAWEI CLOUD Elastic Cloud Servers (ECSs).

You only need to install the migration Agent on the source server. The migration Agent on the source server registers its connection status with SMS and completes the migration feasibility evaluation. After confirming that the source server can be migrated, you can create a migration task. SMS migrates OSs, applications, and files of the source servers to ECSs on HUAWEI CLOUD.

Figure 1 SMS working principle

SMS works as follows. SMS automatically performs the migration, and you only need to perform 1 and 3 by yourself.

  1. Install the migration Agent on the source server.
  2. The migration Agent installed on the source server registers its connection status with SMS and reports the information about the source server to SMS. Then, SMS completes the migration feasibility check.
  3. After the migration feasibility check is passed, you can create a migration task.
  4. The migration Agent obtains and executes the migration instruction sent by SMS.
  5. SMS starts to migrate system disk of the source server.
  6. SMS starts to migrate data disks of the source server.
NOTE:
  • Source end: indicates the source server in a migration task.
  • Destination end: indicates the destination server in the migration task.
