I was about to ask about AWS migration, but found it addressed on SO. That question is more than 60 days old, and therefore it can't be migrated (I believe). Still, it's a DBA-related question, and the answer may change as Amazon adds capabilities. It would be valuable to have it - or a copy of it - here.
In such circumstances, should one create a new question on DBA.SE, assuming that the SO question cannot be migrated?
