In VMware vSphere, users may need to migrate virtual machines (VMs) between ESXi hosts utilizing different generations of CPU hardware. Configuring Per-VM Enhanced vMotion Compatibility (EVC) assigns specific CPU feature baselines to individual virtual machines, allowing seamless live vMotion operations across disparate host CPU architectures without requiring a guest operating system shutdown, provided the target baseline is lower or equal to the source capabilities.
VMware vSphere 8.x
Standard deployment requirements for cross-generational hardware cluster migrations and infrastructure modernization strategies.
Power off the virtual machine if you are downgrading the EVC mode. (Note: If you are enabling EVC for the first time or raising the EVC mode baseline, the virtual machine can remain powered on).
Per-VM EVC configuration details can be validated against the official domain documentation.
