Enhanced VMotion Compatibility (EVC)

Enhanced VMotion Compatibility (EVC)

Enhanced VMotion Compatibility (EVC) is designed to ensure the CPU compatibility between ESX hosts. EVC leverages the Intel FlexMigration technology as well as the AMD-V Extended Migration technology to present the same feature set as the baseline processors.

This means if we have different CPU on Hosts from same vendor/family (Intel/AMD) we can do migration by enabling EVC mode.

We can’t use the migration if we have CPU’s on hosts from different vendors.
