Suite Creating A Test Site - Article
 

When a new version of vBulletin comes out, there's always a clamour to get upgraded as fast as possible While in the case of bug fixes, the need to upgrade quickly is understandable, too often on the forums we see people that haven't considered what effect an upgrade will have on their site.

As a result, many people don't test an upgrade, sometimes because they don't know how. The article linked below should, hopefully, help to bring that knowledge to more people and help you make your live upgrade run as smooth as possible.
