I'm creating a cloud formation template that I would like to use to run and create an environment. The only problem is that I have an existing database that I would like to form a part of this stack.
Can I 'swap' an RDS instance within a stack if I were to launch my cloud formation stack that contains an RDS instance once I have set it up?
I can't see any other way of doing other than to back up my database, take it down and then bring it back up again from the backup.
