CMS How to mix old with new?
 

I've had nothing but complaints since I upgraded from 3.8.4 to the vB4 Suite. I'm sure most of it is due to change being hard to accept and the fact that some of the hacks/product add-ons were lost but:

What would be the best way to have the forum tab redirect to the old style forum? Is it feasible? Would the two be compatible as far as usernames, etc? Would I have to work out of two different admincp's? Can they interlace at all?
