Hello,
I'm running a 2.0.3 forum with several hacks and Major template chages.

Anything I should know before I start to upgrade?

What do you recomend?:
1. Upgrade the forum (not db). (analysing code to keep hacks)
2. Clean install, reinstall hacks and templates.

The forum is working perfectly now, so i'm a bit ancsious to mess it all up..

I realize that some hacks might not be compatible with v.2.2.1, but that question should be posted @ vbulletin.org, right?

Any input would be appresiated.
