World Server Shuffle Dates and Query

[Rosentretter]

My question here is this: will the free transfers be available within EU or NA data centers only, or whenever we get the free transfer period we can move from NA to EU or viceversa?

EDIT: Will the new servers in Chaos and Light be added in the same day the redistribution happens? I'm concerned about this matter also because of housing. What if I wanna move to an EU server for free, but by the time I can, already every house is taken by other players?

I think almost all of us can agree that in the period of these transfers, something as important as housing should be locked... I guess.
