Managing data migrations
After using the Migrate data from EC2 database action from the RDS console, Aurora starts the migration automatically.
If you used the AWS DMS console to create the migration resources, you can start the migration process.
Starting the data migration
Follow these steps to start data migration:
Starting a data migration
-
Choose the target database on the Databases page in the RDS console.
-
In the database details page, choose the Data migrations tab.
-
Under the Data migrations tab, the Associated data migrations lists the available data migrations.
Migrations set up using the Aurora console start automatically once the required resources are set up.
Migrations set up using the DMS console are set to Ready.
To begin these migrations, select the Actions drop down and select Start.
-
This begins the data migration for your EC2 database.
Stopping the data migration
For data migrations whose replication type is full load, stopping the migration causes the process to stop and can't be resumed. Once stopped, you must restart the migration.
For migrations with replication type set to change data capture (CDC) or full load and CDC, you can stop the continuous replication process, and resume the process later.
Stopping a data migration
-
Choose the target database on the Databases page in the RDS console.
-
In the database details page, choose the Data migrations tab.
-
Under the Data migrations tab, the Associated data migrations lists the ongoing data migrations.
To stop a migration, select a data migration and select Stop in the Actions drop down.
-
This stops the data migration for your EC2 database.
Resuming the data migration
For data migrations whose replication type is full load and change data capture (CDC) or change data capture (CDC) migration, you can resume the CDC process from the last stop point.
Resuming a data migration
-
Choose the target database on the Databases page in the RDS console.
-
In the database details page, choose the Data migrations tab.
-
Under the Data migrations tab, the Associated data migrations lists the stopped data migrations.
