There is no good way to do this at the moment. The cloud domain is used and possibly stored inside a lot to gear and cartridge configurations as well as DNS.
Changing the cloud domain using puppet will work for new applications but will cause existing applications to break.
Is there a reason you need to change the cloud domain? perhaps we can think of an alternative?
