You can set the default compatibility for virtual machine creation on the host, cluster, or data center. These options ensure that when virtual machines are added to an existing vSphere environment, they are compatible with the host versions that reside there.
The following conditions apply:

- A default compatibility setting on the host overrides a default cluster or data center setting.
- A default compatibility setting on the cluster overrides a default data center setting.
- On the host or cluster:
- On the data center:
Note: You can set the compatibility only on hosts that are not part of a cluster.
When you change the compatibility for a cluster, the compatibility for all hosts in the cluster changes as well.
When you create a virtual machine on one of these objects, the default compatibility setting is used.
