I've just recently completed an import from a large vb forum (83k users) to a new xenforo install. The problem seems to be that although all users were imported, they were imported without belonging to any particular usergroup. In addition, the custom usergroups from the old forum got imported and now I can no longer find the default usergroups in the Xen admin. We also have sonnb groups and galleries on the new xen install that need to work. I need to get this done as quickly as possible. I'm hoping to avoid having to begin a completely new import, and the longer it takes to finish the install in progress the more complaints I'm going to get from surfers regarding missing posts etc. I really want to hire someone VERY expert with xen to get this done and in the rear view mirror once and for all. Please pm me for details if you're interested.
