I love vBulletin 3.x and have refrained from upgrading to version 4. I am genuinely interested in purchasing a XenForo license to give it a try with one of my forums. Keeping that in mind, once I have started to use XenForo, if for any reason I want to switch back to vBulletin 3.x, is there an importer or easy method to do so?
I hate to be the bearer of bad news, but the product you know as vB3 is dead.
The future of vB3 is vB4.
The company that made vB4 will make vB5 (unless they go bankrupt).
Why would you keep with vB3 ? Are you hopeful about vB5 ? Really ?
