Automation tip: Shut down the server before cutover. Make sure that client is not able to connect to the source server during cutover to ensure data consistency.

After shutting down the source servers, the status of source servers on AWS Appplication Migration Service console will first change to Lagging and eventually change to stalled. This is normal because source server is no longer connecting to replication server, we want to stop the transaction on the source before cutover.
