    I have server 2019 as Vmhost1 and I have a server 2016 as FHC-backup.

     

    The issue I’m having is using the replication feature in Hyperv from server 2019 to server 2016.  I can ping, telnet, to all available ports from server to server.  I can create a new VM on the 2016 server and replicate that to VMhost1 (server 2019).  But not the opposite way.  I cannot seem to replicate from server 2019 to server 2016?

     

    Error I get is Hyper-V failed to enable replication. FaILED TO ENABLE REPLICATION FOR vIRTUAL MACHINE “WEBSERVER” (0X80048016)

    you’ve confirmed firewall rules for relevant ports are open bi-directional on both hosts?

    Are these HV hosts domain members, or standalone?

    Yes…I am able to telnet to ports from both directions.

     

    Yes all machines are on the same domain.

    Windows 2016 only supports VM configuration versions 8.0 and older. If you created the VM on Windows 2019 then the version would be newer and that’s not supported:

    https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/deploy/upgrade-virtual-machine-version-in-hyper-v-on-windows-or-windows-server#BKMK_SupportedConfigVersions

    I did not notice any Windows version requirements for Replica so I assume 2019 to 2016 replicas are supported but I also didn’t find anything saying it was supported. (but that was just a few minutes of searching)

    Can you create the VM on 2016, replicate/export it to 2019 and then see if you can replicate it back?

    I am able to create on 2106 and replicate to 2019…Just not the other way.

    that sounds pretty much in line with what Jeremy said. IF you create on 2016 and replicate to 2019,it’s VM8. If you create on 2019, then it’s VM9 which Server 2016 doesn’t understand
