Moving VM error: Failed to establish a connection because of an unsupported protocol version (protocol version 6.0)

Situation: When move a VM from Windows 2016 to Windows 2012 R2, you may receive this message: Failed to establish a connection because of an unsupported protocol version (protocol version 6.0)

Troubleshooting: 1. This could be CPU compatibility issue, which prevent you move VM between different hosts.

2. Also, any VM’s created on the 2016 start as version 8 for Hyper-V configuration, where as my 2012R2 machines are version 5. If you want to be able to move the VM’s from 2016->2012 R2 you may need to make the VM first on the 2012 R2 machine.  You can’t downgrade it.
