I'm in the process of upgrading my 3 node Hyper-V cluster to 2016 (from 2012 R2). I uninstalled vmm 2012 and retained the database. On another server I installed Server 2016 and VMM 2016 and reconnected to the database. The host status for all three hosts say Needs Attention. It has a WinRM Error (20506) "Virtual Machine Manager cannot complete the Windows Remote Management (WinRM) request on the computerHyper-v-host1.domain.org.
I have my VMM service and admin accounts in the local Administrators group of the vmm server and hosts. For testing purposes I turned off the firewall on my vmm server and still have the error.
What did I do wrong?
Thanks
