SMS Functions

Migration Feasibility Check

After you install the Agent on a source server and the Agent is authenticated using an access key ID (AK) and a secret access key (SK) of your Huawei Cloud account, the Agent automatically reports the source server details to SMS. SMS validates the source server details and determines whether the source server can be migrated. You can view the check results by choosing Servers > Source name > Source Info > Source Check.

Migration and Synchronization for Windows

After a Windows source server passes the feasibility check, you can start the migration on the SMS console. The Agent on the source server executes the migration commands sent by SMS. During the execution, the Agent validates blocks in disk partitions on the source server and migrates valid blocks to the corresponding partitions on the target server. After the full migration is complete, the Agent automatically starts incremental synchronizations. In this period, you can stop the services on the source server and start the services on the target server during off-peak hours.

Migration and Synchronization for Linux

After a Linux source server passes the feasibility check, you can start the migration on the SMS console. The Agent on the source server obtains migration commands from SMS and executes the commands. During the execution, the Agent migrates directories and files from the source server to the target server. After the migration is complete, the Agent automatically launches the target server.

SMS does not support continuous synchronization for Linux file-level migrations. You can start an incremental synchronization manually if needed. Then the Agent on the source server will synchronize incremental data to the target server. When the incremental synchronization is complete, SMS will re-launch the target server. You are advised to stop services on the source server and start services on the target server upon the completion of synchronization. Otherwise, multiple synchronizations are required to ensure data consistency.
