EVC allows you to migrate virtual machines between different generations of CPUs.

EVC-enabled cluster only allows CPUs from a single vendor in the cluster. VirtualCenter and vCenter Server do not allow you to add a host from a different CPU vendor into an EVC-enabled cluster.

EVC is used only when you have different generations of CPUs..

Since they are both from the family and generation then you don’t require EVC to vMotion between them. Having said that it’s probaby still a good idea to enable so that if you add additional hosts in the future, they can easily be added to the cluster.

Kind regards.
