In the next 2 or 3 months I?ll move my ESX 3.5 servers and VCenter to the vSphere, this document looks like a good place to start to make sure I get everything setup correctly. Right now I have 5 ESX servers in the data center and 4 small ESX deployments at the edge all controlled by a local VCenter server. A big question is will I need the extra features of the enterprise plus licensing or not.
