All, I am in the process of upgrading my VM infrastructure to v Sphere 5. Today I created a new VC on win2k8 64 and moved my hosts over. This worked just fine. However, I was told (if I understood correctly) that if the esxi hosts themselves were upgraded from 3.5x to 4.0 the upgrade to 5.0 is not supported.
Can anyone comment on this? I am not sure if my hosts fit this criteria as I didn't set them up. Is there a way I can check and be certain they were/n't upgraded from 3,5?\
