I'm a current vBulletin user and after much headaches with the security of the software and lack of support, I've decided that I wanted to switch to a new forum software. I'm currently looking at both xenforo and iPB. One thing I like about xenforo is that it has an importer built into it. So I decided to create a demo forum to see how it works, and the importing of the Usergroups, Users, Buddy/Ignore lists, and Profile Comments all work. No other data gets imported. I'm worried about the forums not being able to import as a whole. I'm currently using vbulletin 4.2.2 PL1.
