As a means to provide more flexibility to play with your friends, or move to a realm that may better serve your needs, we are reducing the cooldown of the Paid Character Transfer service from 30 days to 3 days. This should prove particularly beneficial to players who move to a realm they don't enjoy and wish to quickly move to a brand-new realm. For more information, please see the Paid Character Transfer FAQ -
