Explanation

https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/encrypt-an-existing-amazon- rds-for-postgresql-db-instance.html When the new, encrypted copy of the DB instance becomes available, you can point your applications to the new database. However, if your project doesn't allow for significant downtime for this activity, you need an alternate approach that helps minimize the downtime. This pattern uses the AWS Database Migration Service (AWS DMS) to migrate and continuously replicate the data so that the cutover to the new, encrypted database can be done with minimal downtime.
