Yup , latest ESX version > 2) Shutdown a Guest, Move from Cluster A to Cluster B (migrate option > in > VC) And no problem migrating from ESX 3.5 to vSphere v4? No upgrade prerequisites for the VMs? (I've migrated between hosts often, yes) Ive had no problems, the only prereq's are the after the fact ones stated below > 3) Turn on, upgrade VM Tools to latest > 4) Shutdown, upgrade virtual hardware "upgrade virtual hardware"? In what way and why? Is that something that vSphere requires? I don't need to change the specs on my VMs, if that's what you're referring to here. The VM version in vSphere is 7, you do a right click on the VM and it's an menu option , it has different improved "hardware" IDE, SCSI, PCI Bridges etc... while you don't have to do it at one point you won't get 100% of the benefit of running in vSphere, I've yet to have an issue doing this as long as you do the tools 1st which contains the drivers for the new hardware > 5) Turn on, run windows update in case you need Stuff like "AMD Opteron" > / "Intel" updates > 6) Rinse and Repeat for all guests Sounds manageable enough.
