Guys,

We're looking to establish a new HA cluster with Essentials plus license - using 3 different hosts:
•      Proliant DL360 G7 - 2x Xeon E5620 CPU's 2.4 Ghz (8 cores total)

•      Proliant DL360 G8 - 2x Xeon E5-2640 CPU's 2.5 Ghz (12 cores total)

•      Dell Power Edge R720 - 1x E5-2620 CPU

My question is; will I be able to run vMotion (live migration) between those different CPU's?

Thanks in advance

yes
a place where i used to be had servers in a cluster with a few different xeon models and vmotion worked fine
the guest only detected a new cpu and said it found new hardware but continued to work fine

problem comes in where you have amd and intel systems
the model doesn't matter but have to be from the same architecture; all intel or all amd

this article has many questions around vmotion you might find useful

Yes but you will need to enable an EVC profile baseline.

That will work but check if your VMs will be affected.

Enabling EVC can reduce VM performance if VM need instruction sets common to newer processors.
