Onyxia Char transfer to Icecrown ?

When the Onyxia realm ends, will there be a character transfer to Icecrown?

Also wondering this.

I don't think there was ever official answer regarding what the end-game for Onyxia will be.

If they decide to do it like Frostmourne, with seasons (meaning full realm reset), then I think it's highly likely that persisting Characters will be able to transfer to Icecrown realm.

If they decide that Onyxia will be just another realm onwards, frozen in progress like Lorda and Icecrown, then Characters will just be on that realm - with maybe the possibility to realm transfer to Icecrown.

But who knows at this point

EDIT: https://forum.warmane.com/showthread.php?t=483899 check this post, there was an in-game message upon login, that said that characters are planned to be transferable to Icecrown when the realm will finish. I guess this is the closest to an official answer you will get right now.
