just wanted to give everyone an update.
I was able to setup a test forum rather easy. Had a chance to figure out where things go for the most part and practiced upgrading.
Today, I finally upgraded. All my earlier worries were very unfounded. The upgrade process in total took 15 mins, and the board is fine. Later this evening, I have the "fun" task of putting in 3.6.8 plugins, adding skins and adding suggestions which Brandon made to me when I first signed on.
To anyone that has been thrown in the deep end, I can state from experience that the key is getting up a test board. Get familiar with vbulletin's features, where things go and then apply what you've learned to your actual board.
Thanks everyone for your help. Greatly, greatly appreciated!
