vBulletin 3.6.8 To 4.0?
 

Is this going to be a simple upgrade if I want to go from 3.6.8 to 4.0? I want to update to a newer forum but don't want to wreck my board or lose my database.

Not sure if this was the right place to post this* but seemed like a good place to start. Mods* please move this with a redirect if need be. Thanks.
