vMotion Error
We just added a 4th host into our cluster -- DELL R420. The other 3 older hosts are DELL 2950.
(3) DELL 2950 - 2 CPUs - Xeon E5420
(1) DELL R420 - 2 CPUs - Xeon E5-2450 (10.0.128.4 is the new host)
When trying to vMotion to this new host we are getting the error message below. vMotioning to older hosts is not a problem.

We currently do not have any VMs on the new host. If we turn EVC ON and set it to Merom Generation and migrate all the VMs to the new hosts, what will happen when we retire the old hosts? We will want to turn EVC off at that point.
Does that mean we will need to power off all VMs and then power them ON in order to:
1) Allow vMotion (without EVC turned on)
2) To take advantage of new generation CPU features
???

In other words, just confirming, after retiring old hosts, we can safely turn off EVC. After doing that, we will still need to power cycle the VMs in order to allow standard vMotion and take advantage of new CPU features? (Key point is power cycling the VMs)

Not programming, but thinking that there must be new CPU instructions that can be taken advantage of. Afterall, it has been about 6 generations of CPUs between the old hosts and the new hosts. So I'm assuming there is better technology available in the new CPUs that VMware can utilize.
