It is official. I have our first production system up on a virtual server! The system that I described a few posts ago is working out well (Dell 1750 w/ 4GB Ram). I moved our legacy ACS system with the P to V tool from VM ware and it worked well. As many have said in the past, the VM runs faster than the original! I'm working on creating a Server 2003 Base image now to speed up server setup in the future.
The next system to virtualize will be our current ACS system to aid in testing for patches. Ideally, I will have our production ACS virtualized so that I can create a clone of our running system and apply the patches to it to see what the effects would be to our actual system. I'll post how that goes when we get to it.
