Hi there xF, We're currently running VB 4 on our forum with around 4 million posts, 45k threads and 40k members. We're seriously considering the possibility of migrating to xenForo soon. Are there any other real-case experiences/scenarios with large boards using the importer? Any known problem, tips and tricks? Anything we should know about the migrating process before going for it? Btw, as you might notice, the forum posts/threads/usernames and almost all content is in Cyrillic. Any know problems with that?
