Per the front page of the lodestone:
To resolve this issue, we will be performing maintenance from September 3, 2013, at 5:00 p.m. to September 4, 2013, at 3:00 a.m (PDT), for the purpose of increasing the number of available Worlds, reducing stress on the Duty Finder servers, and increasing the number of concurrent logins allowed for each server.
It's impossible for them to tell us every single thing they have planned. I would like to think they will offer free world transfers for a short bit, and while they haven't announced anything on it yet, it doesn't mean it won't happen. *fingers crossed*
