Please see the
official announcement
There have been some changes and additions to the text we posted yesterday.
The most notable change is that if you are transferring your character to an existing NA1 account, and you have a player on this account, then the transfer cannot be completed. You need to delete the NA1 character first, this will not be done automatically.
Something we didn't mention in our post yesterday was that your character's alignment will also transfer with your character.
Also it's mentioned that there's a
limited time offer on the 6 month subscritpions during the transfer period. The subscription recurs at the special offer price after the original 6 months are over.
