Migration from Aurora to Aurora Serverless

Question

Hi, my Aurora mySQL database is in production and we would like to Migration from Aurora to Aurora Serverless v2. I found this: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-restore-snapshot.html
My question is, on restoring the database as serverless v2 from the snapshot, will the database automatically be used in production instead of the Aurora provisioned cluster that I already have? I have a multi AZ deployment.

Will there be any downtime, if any? Also, what is the amount of time for the Serverless v2 database to be deployed into my production environment take?

Answer

Here is a knowledge center article that explains how to perform this migration:

On the other hand, if you wanted to perform a migration with close to 0 downtime, you should use AWS DMS. Create a source and a destination in dms then start the replication task, which copies the existing and new data with CDC (change data capture). Then make your application point to your new database and done
