Will the nuwiki to vaultwiki importer work if my vbulletin has already been upgraded to the 4 series? Or do I have to do it before I make the upgrade to vbulletin 4x from 3x?
And can the pro installation be purchased separately, later? I think I can do this myself, but want to know just in case. And if so, would there be an extra charge to purchase them separately?
