I am familar with VMware ESX 3.5 P2V Migration in  a production enviorment. And need some advice  for a client that has a a few old Windows 2003 Enterprise servers .They have a heavly used Windows 2003 Enterprise Termiinal Server on a server hardware that cannot he upgraded past 16GB. I am thinking about seiling them a Dell 710 Server with 80GB Windows 2008 Enterprise with hyper v and use the windows sysinternals disk2vhd utility to raise the performance of the Windows 2003 Enterprise Terminal Server. Any suggestions.

The first thing I would do is determine if the TS is 64-bit or 32-bit. If it is 32-bit, big chances if is actually not performing as its best considering PAE would be in use to see above 4GB. Regardless, the 2GB kernel limit would still apply even with PAE.
Given that I would create multiple smaller TSs (4GB RAM on them). That would give you the best performance.
Just keep in mind if you virtualize all in a single host, if that guy goes down, everything is dead in the water. Ideally, on any virtualization project you have at least two hosts.
Also keep an eye on IOPS on the disk. The more disks and the faster these are, the best performance you will get.

The TS will run in one host and if that one fails, it will start again, automatically, on the second host.
So ideally you balance the VMs across the two hosts (let's say, three VMs on host one, four VMs on host two) and in case one dies, the VMs that were running simply start on the second host.
Way better solution.
