Is it possible to restore my previous character in Frostwolf?

Hi All,

I recently just decided to come back playing WoW and I was wondering if it's possible to restore my previous character in the Frostwolf realm if I upgraded to Mists of Pandaria. Since if it isn't possible then I might as well keep my Cata game and play on the cata realms :)

Thanks!

During Moltdown, all data of the molten realms were lost.
So no, it's not possible to restore it.
