Hi All, I have Implemented ISA server as a cache server on a PC. I have used it as a cache server for almost 2 months. Now I am Upgrading the cache server to a new PC with good configuration, I used cache dir tool and found that there are around 8000 URLs cached in my old server. So, now if I change the server to a newer one how do I transfer these cached 8000 URLs. Do I need to copy only dir. file with cdat extension in url cache directory from old server to newer one or should I need to copy something else? Any inputs would be greatly appreciated. Thanks are Regards, Vinay. MCP+I, MCSE.
