As of now, this is the current status. They aren’t developers or game masters, and they can’t provide an update if they don’t have anything to share. As there was no official confirmation that everything had been given the all-clear, it’s logical to assume that information is not yet available.
This also isn’t anything you paid for, just to set the cards right. They don’t call them free migrations for nothing.
They aren’t in the habit of withholding information in the CS forum. When they have more, they will share it.
