Hey Helen, if you have the information of the size, the cost and the speed of the migration from x to Aurora vis DMS for your use cases I know that is high-value knowledge to share since the docs don't really give you examples.

I recently assisted migrated a 10 million row database from Postgres to MySQL Aurora Serverless and the migration was done in under 10 mins. I believe the cost was negligible but I personally don't remember.

DMS is as you say a fiddly tool

Hey Andrew

That is an excellent question. From my understanding, the DMS services are free if you are moving to Aurora so the only costs are the CloudWatch logging that went along with it - aws.amazon.com/dms/free-dms/

I'll check back and let you know if that's not the case

Just a quick check for transfer:

All data transfer into AWS Database Migration Service is free, and data transferred between AWS Database Migration Service and databases in Amazon RDS and Amazon EC2 Instances in the same Availability Zone also is free. Standard AWS data transfer rates apply when you migrate your source database to a target database in a different Availability Zone, Region, or outside of AWS. Standard AWS data transfer rates are listed on the EC2 instance pricing page.

The cost comes down to the server used and duration it ran, so knowing what size and how long would be of help
