Checking Migration Results

You can use either of the following methods to check the migration results:

  1. DRS compares migration objects and data and provides comparison results. For details, see Viewing Migration Results on the DRS Console.
  2. Log in to the destination to check whether databases, tables, and data are migrated. Confirm the data migration status. For details, see Viewing Migration Results on the DDM Console.
