If you don't mind me asking, why is the new cluster vSphere 4 and not 5?
My virtual center is 4 and at this point it is not possible to update my Virtual center and i don't want to run 3 different versions in my virtual environment. so that is the only reason i am running 4 not 5
So there is no other way for me to do without downtime ?
even if I migrate with EVC mode on I still have to upgrade the virtual hardware and tools etc.
Thanks again
