How To Migrate an Existing RDS Database
Sometimes you need to move an RDS database from one region to another. How do you do that? It’s actually pretty simple.
- Make a snapshot of your database (Always do this before changing the configuration. It’s just the safe thing to do.)
- Create a read replica of the database in the new region you are moving to.
- Once that is finished being created and is ready, promote it to being master database.
- Change the relevant network configuration to point to the new database.
- Delete the old database
