You can set the default compatibility for virtual machine creation on the host, cluster, or datacenter. These options ensure that when virtual machines are added to an existing vSphere environment, they will be compatible with the host versions that reside there.

Before you begin

Required privileges:

  • On the host or cluster: Host > Inventory > Modify cluster

  • On the datacenter: Datacenter > Reconfigure datacenter

About this task

The following conditions apply:

  • To set the default compatibility on the cluster, the cluster must contain hosts that are connected and not in maintenance mode.

  • A default compatibility setting on the host overrides a default cluster or datacenter setting.

  • A default compatibility setting on the cluster overrides a default datacenter setting.
