Okay, I imported my vb forum yesterday, after a few fits and starts, mostly, as a friend calls them, chair errors. Or in my case, recliner errors. Anyway, after my second start at it, I had my vb profile exactly matching my xf profile and was able to avoid most of the chair errors. Since the vb import had all the posts that an older smf database had where I was listed as a guest account, I avoided that import totally into the vb system. Here was my query yesterday:
http://xenforo.com/community/threads/question-on-user-intergration.7691/
Okay, so I cut the clutter, editing out old posts and accounts no longer needed and cleaned up the vb database. I also made my vb profile match, as much as possible, my profile on my xf copy.
Then I made a backup copy of my xf forum and preceded to import the vb forum. Other than list of duplicate usergroups that I now longer use or need, I had done it easily enough. So I brought up my old forum and my newest xf forum and compared the missing usergroups side by side. The ones listed on XenForo but not at vb, I deleted.
Oh, and this was a 4.0.8 copy of vb I imported. I just didn't have a blog running or a cms. I had been using vbadvanced, turn it out prior to the migrate and wasn't even using the blogs. So I basically imported a forum only copy of vb 4.0.8
