Good question, sir. Yes, the basics would be good and/or the option to choose what comes over would be best. Mainly and this again is just me/us, I'm interested in upgrading our current UBB board to the latest, then bringing over JUST the posts and forums actually from a vB forum. We're thinking about going from public to more private. We have two boards (one vB) and two different user databases, etc. and I'm thinking about consolidating to just UBB -- but not bring over vB users. We'd keep the posts that are already there and bring in the vB posts as "archives" so to speak. Maybe the vast majority of posts would not have usernames you couldn't click on or use, since we'd hold off on importing them, but at least we'd have everything still.
Hope that makes some sense and helps. Thanks, Rick.
