Thanks. I was aware of losing hardware version 8 and 3D graphics.

To that point though, would only the ESXI hosts that store the virtual desktops need to be on vSphere 5, or does the host that stores the View Connection server also need to be on vSphere 5?

In my environment, as mentioned, I have 3 dedicated hosts that strictly store virtual desktops. My vcenter for View is a separate instance, and is a VM, stored on some production server hosts, along with my connection servers
