Not sure exactly when, but the site will be migrated within a day or so. Maybe tonight. I have been slow out of the gate because of work, and missed a window of opportunity to have it migrated earlier today.
When it does, the site will be put into maintenance mode with a message explaining the migration.
Obviously when the nameservers get updated it will take some time for it to propagate.
Some of you guys might want to PM me your email so you can help test when the time comes.
I can help test. I'll pm you my email.
