I haven't wanted to upgrade my custom site in years. Running on 3.5 . Never was a fan of the interface on 4 or the whole fiasco that went on with vBulletin in general. Plus the licensing is now a joke. Found XenForo and it seems exactly what i'm looking at for my upgrade path. Planning on taking my data (Users/passwords/forum layout/threads/posts/possibly polls and attachments) and going to ipb but this software is very interesting. Reading some of the threads here - see the converter is for 3.7/3.8? What would be my import success going from 3.5 to XenForo? Thanks for the help and keep up the great work!
