I have a scenario where I want to move my existing DynamoDB database to the postgressDB database. I already implemented a new system where I can move data via a glue ETL Job and it is working fine in offline cases.
Since my old and new system has active live users, how can I do this Database migration in a live online case? what are the best and most popular approaches to tackling this scenario?
Please share the best usage cases. Thanks in advance!
