What Is SMS?

Server Migration Service (SMS) helps you migrate applications and data from x86 physical or virtual servers on-premises or in private or public clouds to Elastic Cloud Servers (ECSs) on Huawei Cloud.

Figure 1 How SMS works

How SMS Works

You only need to perform steps 1, 3, and 7, and SMS takes care of the other steps automatically.
  1. You install the Agent on a source server.
  2. The Agent registers its connection status with SMS and reports the information about the source server to SMS. Then, SMS evaluates the feasibility of migration.
  3. On the SMS management console, you configure the target server and start the migration.
  4. The Agent executes the migration commands received from SMS.
  5. The Agent starts to migrate data on the system disk from the source server to the target server.
  6. The Agent starts to migrate data on data disks from the source server to the target server.
  7. You launch the target server.
  • Source server is the x86 physical server or VM running on-premises or on another cloud that you migrate data and applications away.
  • Target server is the ECS that you migrate data and application to. The target server takes over the migrated data and applications. During the migration, data on the source server is transmitted based on the migration policy you specify and overwrites the existing data on the target server.
  • SMS is the SMS service.
