ERROR_CLUSTER_OLD_VERSION

ERROR_CLUSTER_OLD_VERSION means one or more cluster nodes run a Windows version that does not support the requested operation. The operation may require a later OS release or a completed rolling upgrade.

What to check

  • Identify every node’s OS build and the operation that requires the newer capability.
  • Avoid enabling a feature that leaves mixed-version nodes unable to participate.
  • Plan the upgrade with validation before and after node maintenance.
