A consideration would be how to transport the data dump files to on-premise.
It is 4TB of large data, so even DirectConnect will take a reasonable amount of time.
It would also take a lot of time to migrate little by little while replicating using AWS DMS or other means.
I think it is essential to provide some downtime.
It is also necessary to test the migration and measure how long it will take.
If you use AWS DMS, please make sure you also have a supported version.
https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Introduction.Sources.html
https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Introduction.Targets.html

The following documents are best practices for migrating to RDS, but it is recommended to review them as the same considerations apply when migrating to on-premise.

As Riku mentioned, DMS is an option. If it's OK to have the DB down during the process so no change data capture is needed it's pretty simple to do.

However native SQl Server backup may be a better option for you - see https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/SQLServer.Procedural.Importing.html.

  • Hi, the best way is to gain some knowledge, starting with the approach and links that have been suggested. A bit of reading and experimentation will get you there much faster than waiting for detailed info from other people that may never come. Getting step-by-step instructions here probably isn't realistic. All the best.
