Operation Description

  • You can call this operation to cancel the migration task before data migration.

Note Before you call this operation, ensure that a one-click upgrade task has been created for the cluster. You can call the CreateDBCluster operation to create an upgrade task. Set the CreationOption parameter to MigrationFromRDS. For more information, see Create a PolarDB for MySQL cluster by using the Migration from RDS method.
