As I mentioned before in another thread, potentially best solution for largest number of players. If they just merged one server into another, neither would really have any choice in the matter. No one would be able to relocate if say both of the merged servers had low population for their timezone/language. It's not complicated at all really. Everyone choose a new server. Players can coordinate their choices instead of it being completely forced.

My only issue is future returning players not being able to select a server and being distributed randomly.

Edit: The only difference between this and Rift is that we're not being given suggestions, as far as I understand it at least.
