Active fan site for artist Morrissey started in 1997. Just moved over from vBulletin 4 - 1.6m vB4 forum posts since 2006. About 3000 vB4 CMS articles since 2011 also ported over to use XenPorta 2.
I began evaluating the possibility of a move a few months ago and it was clear early on this would be the best course of action. All the main features and functionality I needed were provided for by the core software or through plugins. The move was smooth sailing for the most part. Great to be part of the XenForo community now!
