Is there an import to vB4?


I have both vBulletin and xenForo keys. I really disliked vB4 and was really looking forward to transferring my vB3 forum to XenForo but haven't had time until now. Now I don't know what to do. I absolutely hate Internet Brands as a company and I don't want to stand against Xen Foro but I also don't want to be trapped on a sinking ship.

If I go ahead and transfer my massive forum over to xF and it goes under, is there support available for getting my database back to vB?

Appreciate any advice and good luck xF, I hope you win and counter sue for damages after this is all over.
