I had to migrate my 1.1 TB Windows Home Server from a physical ESXi server I had running on my home network to my new Dell 8500 Desktop. Instead of doing a V2V over the network I just took the disk out of the ESXi server and put it in the new Dell desktop and booted the ESXi server as a VM from the hard disk. Saved a ton of time.
