according to one of the gm’s the other night, the current plan (subject to change, i am not staff, and whatever other disclaimers might apply)
basically, your team will be lifted from the current server, and simply over-write whatever team/characters are on the destination server.
in other news, paid transfers are not a thing. (yet.)
maybe after they’ve gotten all the launch issues taken care of, then they’ll consider it, but in all probability, it likely won’t be available for several months. (thoughts on that below.)
additionally, it will likely be pretty much the exact same thing as the complementary one-time regional transfer. that is to say, tokens and other active “services” won’t be transferred.
server transfer is only an issue now because they did not expect such high popularity, and they did not expect that regional location would be such a significant issue for playability.
once launch issues are sorted and the current transfers are completed, it’s unlikely to be much of a priority. from that point, everyone -should- be on a server that is regionally close to them, or they’ve chosen to remain on a less-optimal server for some reason. new players would either pick a close server, or their friends’ server with the awareness that if it isn’t a close server, it might not play well.
after that, server transfer isn’t likely to include any extra benefits, and all the players should already be where they want to be, so seems unlikely that it would be much of a proprity.
