Enable EVC in vSphere 5.5 without downtime

Hi Experts,

I need to enable EVC in my production VMware cluster since we bought three blade servers with different CPU version. Will it be possible to enable EVC in cluster without shutting down existing VM Guest OS. Actually I am trying to avoid downtime, at the same time if I enable EVC in cluster, does it have any negative result that might impact Guest OS. Appreciate if you please give me any reference link that might help me to understand the details.

Thank you Guys for the details insight of this issue and apology for replying late.
I am now following the below procedure:

I have created a new empty cluster and then enable EVC and then move the two same CPU compatibility EXi hosts on to this cluster and notice some networking issue and which is fixed now.
Shutdown guest OS and moved some less critical system into the new cluster and everything is working perfectly.

Now I will move one of the ESXi hosts(which is different CPU version) into the new cluster to see any issue and start moving Guest OS gradually, but for moving Guest OS, I am shutting down the VM and moving it.
Thank you once again.
