I think your overthinking this, I am pretty sure by march they will have elaborated on how it will work and even give the server names. despite what everyone rages about with posts , SE really dosnt let us down that much. everyone thinks its the end of the world when they implement X but when ti happens everfyone ends up happy with X. besides the migration to the 2.0 servers were gonna be like this anyways, if anything it gives you a what to expect feeling and it lets SE notice and correct any difficencies tehy encounter with a server merger/Transfer. All in all things will be fine
