Can I migrate an existing Aurora DB cluster to Aurora Serverless?

AWS Aurora FAQ states:

enter image description here

I have a snapshot of an existing Aurora (Postgres) provisioned cluster. The snapshot was originally taken in us-west-1, but I copied it to us-west-2 (not sure if this matters). When I attempt to restore this snapshot to an Aurora serverless setup, I only see the option to create a provisioned cluster.

What am I doing wrong?

Aurora serveless supports only version 10.12. Maybe your regular aurora had different version? – Marcin
That appears to be it - my 10.14 snapshots do not offer serverless, but 10.12 snapshots do. – Josh

You can do it via snapshot -> restore, but only if your source database snapshot has specific characteristics (as of April 2021):

  • Aurora (MySQL 5.7)2.07.1
  • Aurora (MySQL)-5.6.10a
  • Aurora PostgreSQL 10.12

The versions that are compatible to swap back and forth (using snapshots between serverless and provisioned) change over time. If you are using a source database snapshot that is not directly compatible, you can try mysqldump.
