Can you mix Windows Server 2012 and Server 2012 R2 in a cluster?

Q: Can I create a cluster with a mix of Windows Server 2012 and Windows Server 2012 R2 hosts?

A: No. You can't mix OS versions in a cluster. It will fail validation and also will fail to create the cluster. All OSs in a cluster must be the same version.

This is why a rolling upgrade of a cluster isn't possible.
