Any significant server application may require significant effort to reinstall/reconfigure. Be careful when following advice like “….personally will go for the new install mechanism rather than the upgrade. This is because I find the ESX install quite straightforward and easy and rebuilding an ESX host can be done in very little time at all. With the rebuild process very quick for ESX and most management and configuration elements configured from Virtual Center, ESX is unique in build time requirements.”….

I would look into platespin if vmware does not provide a server upgrade technique you can use.
