Vikas,
So the bottom line is that I will not have any resistance from the 4.1 vCenter control. The Host will come over the the 5.5 side without issue or resistance, then?
Thanks for the other links as well. The old servers SuperMicro's and the new are UCS 220 M3's, so I am likely to have to enable EVC to execute the vMotion I need.
Nice write-up and I appreciate the quick response.
