No matter what stage of a service you are at you should have a documented procedure (ideally running a script) that can stand up a working instance of the system.
This has vast benefits for agility and fast development when developers are not always fighting the build system and have a "no fear" attitude about deployment.
If you have that, you can build a system in another region and be able to migrate wholesale to another region with more capacity and not be particularly concerned about the general problem of coordinating the service across multiple regions at the same time.
