I checked the archives and this has been covered before but I have an additional question. I inherited an ISA 2000 server with a 120 day evaluation copy of the software installed. Eval period is up and we've purchased the licensed copy like good little kids. I got from previous posts that I can run the retail install over eval install but what will happen to the current configuration? Is there a way to do this without having to reconfigure the ISA software? Thanks in advance, Scott.
