B, renew, upgrade your 6.05 to UBB.Classic 6.7.3, then "convert" your forums to UBB.Threads 7.

If you don't want to go through all the work of upgrading and then importing to the new product you could always hire a developer (likely one of the glorios mods here, such as myself, Allen, ron, etc) to do all the hard work for you.

I am a Web Development Contractor, I do not work for UBBCentral. I have provided free User to User Support since the beginning of these support forums.
Do you need Forum Install or Upgrade Services?
