Sorry for the delay - I've been away for a few days. Thanks for the reply. I'm aware that I am able to replcae the hardware,. That is already in progress.
My question is whether it is a good idea to replace Server 2.0 with Workstation and whether there would be any issues asociated with that.
I think one of the main differences is that VMware workstation does not run as a service, meaning if you log off, the application closes and thus your vm's shut down. The shutdown process is also not very clean. I did find articles on google that have "workarounds" that might work, but personally I have not tested it myself. With VMware server, you have the option of running it as a service.
With that said, I do believe that VMware workstation has a lot more functionality then VMware server does. I personally use workstation to testing purposes, and I would not run anything that requires to be up at all times. Also the VMware Server 2 support ended in June 2011 so if support is something you require (good to have if you're running production systems) then I would look for another solution. There's lots of good info on VMware workstation vs VMware server on google and this forum here.

Is this still completely true with Workstation 8's Shared Virtual Machines? I have seen anecdotal evidence that shutdown isn't always clean, but I thought the shared VMs really do run as service - level VMs.
