We are planning to add new servers to our existing vSphere 5 environment. We have 3 BL680c G5 (Intel Xeon E7330 processor) and planning to add a few BL680cG7 (E7-4800 Westmere family). Will EVC allow me to vmotion between them? Any other things I need to know before doing EVC? Thanks!
You have to enable EVC baseline for intel processors called Intel® "Merom" Generation (see link below) both processors are compatibile with this baseline.
Remember to enable EVC BEFORE you add new servers into existing cluster
Thanks for the info. If I enable EVC before adding the new servers, then it will add perfectly fine without shutting down the VMs? As i am seeing some posts to create a new cluster and enable EVC and then slowly start to migrate the hosts to the new cluster.

you are welcome, hmm ... I'm always forgetting how I did that, (I have to do some test in my lab and document it) my answer is - you can test by yourself - it is a harmless operation. Enable EVC, add new host into existing cluster and try to make vMotion - the worst case scenario is you will get incompatibility error before migration starts. Let me know what's results. If you don't want to risk, I can do some test in my Lab and let you know.
Sorry for getting to you back so late, I did testing, no outage for VM when you enable EVC before you add new server into cluster
