Starting a Full Replication

Scenarios

A full replication replicates all data from the source server to the target server. The replication speed depends on the outbound bandwidth of the source server or the inbound bandwidth of the target server, whichever is smaller.

Constraints

After a full replication starts, do not restart the source server or Agent, or the migration will fail.

Prerequisites

  • The target server has been configured. For details, see Configuring the Target Server.
  • The migration task is in the Full Replication stage and its status is Ready.

Procedure

  1. Sign in to the SMS console.
  2. In the navigation pane on the left, choose Servers.
  3. Locate the source server and click Start in the Migration Stage/Status or Operation column. In the displayed Start Migration window, click OK to start a full replication.

    You can also select the source server and click Start above the server list. In the displayed Start Migration window, click OK.

    During the full replication, the target server is locked by default, and you are not allowed to perform any operations on it. After the migration is complete, the target server will be automatically unlocked. If you need to perform operations on the target server during the replication, unlock the target server.

  4. In the server list, click the name of the source server to view the migration progress.
  5. Wait for the full replication to complete.

    • If you set Enable Continuous Synchronization to No when you defined the migration settings, after the full replication is complete, the migration will go to the Target Launch stage, and the target server will be launched to complete the migration automatically.
    • If you set Enable Continuous Synchronization to Yes when you defined the migration settings, after the full replication is complete, the migration will enter a Continuous sync status, and any new or modified data will be automatically synchronized from the source server to the target server. You will need to manually launch the target server to complete the migration. For details, see Launching the Target Server.

    After the migration and service cutover are complete, you need to adjust the configurations of the target server based on service requirements. For details, see What Configuration Items Need to Be Manually Modified After a Server Is Migrated?
