Creating a DRS Migration Task
Create a DRS migration task to migrate data from RDS for MySQL to DDM in a different region.
Pre-Migration Check
Before you create a migration task, check whether migration conditions are met.
This section describes how to migrate data from RDS for MySQL to DDM. For details, see Before You Start.
Creating a Migration Task
- Log in to the management console.
- Click
in the upper left corner and select region CN-Hong Kong.
- Click the service list icon on the left and choose Databases > Data Replication Service.
- On the displayed page, click Create Migration Task.
- On the Create Replication Instance page, select a region and project, specify the task name, description, and the replication instance details, and click Create Now.
For details about parameter description, see From MySQL to DDM.
- On the Configure Source and Destination Databases page, wait until the replication instance is created. Then, specify source and destination database information and click Test Connection for both the source and destination databases to check whether they have been connected to the replication instance. After the connection tests are successful, select the check box before the agreement and click Next.
- On the Set Task page, select a migration type.
Migrate Object: Select Tables.
- Click Next. On the Check Task page, check the migration task.
- If any check item fails, view the cause and rectify the fault. After the fault is rectified, click Check Again.
- If all check items are successful, click Next.
- Click Submit.
Return to the Online Migration Management page and check the migration task status.
It takes several minutes to complete.
If the status changes to Full migration, the migration task has been started.
- For migration from MySQL to DDM, full migration and full+incremental migration are both supported.
- If you create a full migration task, the task automatically stops after full data is migrated to the destination.
- If you create a full+incremental migration task, a full migration is executed first. After the full migration is complete, an incremental migration starts.
- During the incremental migration, data is continuously migrated so the task will not automatically stop.
