I am reasonably certain that characters will not be able to be transferred from Legacy to non-Legacy servers for another 5+ months or so, as Yoshi-P has mentioned. I really wish they'd add at least one new server that allows 1.0 characters to transfer to it too, though. There are a whopping four US Legacy servers and I can't be the only 1.0 player that is starting to feel a little cramped. >.<

As for players transferring to the brand new servers from the previously existing non-Legacy servers? It'd be pretty ridiculous if it was not allowed and I can't see that sort of restriction happening.
