UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support convert snitz forum (ASP) to UBB 6

i have a snitz forum right now ( http://forum.snitz.com ) and i know there is a way to convert UBB to snitz. but i was wondering if there is any way to convert snitz to UBB 6?
i would really like to use UBB as the message board on my website, but i dont want to lose the current members and their posts. so i was just wondering.
thanks
