Server 2012r2 hosts live migration authentication failing

I'm adding a replication host to my current environment.  There are now two servers running Windows Server 2012r2.  I am managing from a Windows 10 workstation.  I have both a physical & virtual AD server at 2012r2, through which I've enabled delegation for both the CIFS & Windows Virtual System Migration Services.  On both computers in Active Directory, I've added both hosts & their FQDN's to enable these services.  

Authentication is still failing when using the 'move' feature in Hyper-V manager.

Thoughts on something I may have missed?

What happens when you try to run the commands from the server itself?
As a domain admin?

Flip both host's delegation properties to Trust this computer for delegation for any service then restart the VMMS on each host.

A reboot _may_ be required.

What AD Domain/Forest level?

Well, I am a bit confused as to what you are trying to do...

If you added a *replication host* to your environment, you'd never "move" a VM or use live migration. Hyper-V Replica already has a full copy of the VM on the replica target. You'd instead use the "failover" set of commands.

If you are *not* configuring a replication host, we'd need to know more about your setup. Is there shared storage involved? Are you trying to perform a shared-nothing live migration?  Is there a cluster?

I cleared this up...it was quite simple, my configuration of Kerberos authentication within Hyper-V Manager for each of the hosts did not take.  It was still set to CredSSP.

This purpose of this project is both a migration and to setup a replication host.  Having installed Server 2012r2 host in 2014, on an HP ProLiant DL360 G8 server, with 2TB of on board Storage and 64GB RAM...I decided to use the new HP ProLiant DL360 G9 with 8TB on board, and 192GB RAM in production moving forward.

The plan was to setup the new 2012r2 host, migrate all current VM's to that host...then configure replication to the old host after a small RAM upgrade and some maintenance to the older machine.

The replica server will be moved to a remote location once that part has been configured.  I wanted to be sure that the new production server was running properly as my primary, prior to configuring replication to the older hardware.  So, I don't know that "never move a VM or use live migration" is an accurate statement.  I understand I wasn't very clear on that.

Configuration of Authentication on host did not apply...double checked & was successful.
