The largest issue i see for this is RDS. If you use RDS...i dont know, but migrating away is not going to be easy.
Migrating the servers themselves however shouldnt be too hard if you have a fairly sane build process, however if you dont, and i suspect a lot of people dont...its not going to be fun.
