Why won't it let me transfer world to Phoenix?

Is it to do with it being full or something? Should I just keeping checking Mog Station every day to wait until it shows up on the list?

Thanks. I really want to move there as all my friends are on it.

Yeah Phoenix is one of the Most Pop servers So I'd imagine it is full. Check Mog station and hopefully a space would free up for ya.

If you've already maxed out the character limit on Phoenix you won't see it listed either.
