I'm considering migrating from vBulletin 4.2.5 Suite to something more modern (better security, more mobile friendly, better SEO characteristics, responsive design, etc.)...and would like to retain as many of the built-in features of vB4 Suite (CMS, Blog, RSS, reputation system, etc.). I know there have been lots & lots written on this subject...and I've read thru many many threads & articles via search engine results...and I'm still sort of confused what platform to upgrade/migrate to. * Xenforo seems to be well liked...but from what I'm reading...when Xenforo 2.1 is purchased...it's basically just the forum software (no blog, no CMS, etc.). * Xenforo is supposed to be very plug-in friendly...plug-ins cost extra...and unless I'm not finding the correct Xenforo plugin sites...I'm not seeing a lot of plugins for Xenforo 2.1 (blog, CMS, newletter, reputation system, etc.). Basically plugins that would replicate many of the built-in features of vBulletin 4.2.5 suite....that might be lost migrating to Xenforo. I'm seeing lots & lots of negative comments about vBulletin 5 ("vB5 sucks", "vB5 stinks", "vB5 is crap", "don't use vB5"...etc.). What I'm not seeing much of is WHY is vBulletin 5 bad. It would seem that if someone had no additional facts...upgrading from vB4 to vB5 would be the obvious & logical thing to do (similar built-in feature set, less of a learning curve, etc.). Given the information above...two questions: 1. Can anyone comment on why vBulletin 5 is bad (specifically)? 2. If my goal is to retain as many built-in features of vBulletin suite 4.2.5 as possible...and upgrade/migrate to a more modern platform...what forum software makes the most sense to upgrade or migrate to? Thanks very much.
