your best idea is to upgrade to most recent version, the most compliant version if you want to upgrade to vB 3 is vB 2.2.9. anything before 2.2.9 is not compliant for an upgrade to vB 3. I think your best idea if not wanting to leave vB 2 is fully upgrade to most current version of vB 2(2.3.5 ?)and stay on top of patches,fixes, and versions as any vbulletin webmaster/mistress should
