Can I Change the Source or Destination Database After a DRS Task Is Created?
When a DRS task is in the Configuration state, you can change the source or destination database.
- For a to-the-cloud task, the source database can be changed, but the destination database cannot be changed. The destination database is the DB instance selected for creating the task and cannot be replaced. Only the database connection information (username and password) can be modified.
- For an out-of-cloud task, the destination database can be changed, but the source database cannot be changed. The source database is the DB instance selected for creating the task and cannot be replaced. Only the database connection information (username and password) can be modified.
- For a self-built-to-self-built task, you can change the source and destination databases.
After a DRS task is submitted and started, the source and destination databases cannot be changed. Only the database connection passwords can be changed.
