Hi,
We've several 2016 clusters and VMM 2016. Live migrations between clusters and standalone hosts was 100% ok. Network configurations with VMM was 100% ok too.
After upgrading one of the clusters to WS 2019 and VMM to 2019 the problems started.
The VM's live migrated from 2016 cluster to 2019 cluster. Now live migration from 2019 to 2016 (clusters) fails with:
"Error (12700)
VMM cannot complete the host operation on the xxxxxxxx.edu.com' server because of the error: Virtual machine migration operation for 'zzzzz' failed at migration source 'xxxxxxxx.edu.com'. (Virtual machine ID FDBC40ED-634C-4EBD-A645-5CE816B55D13)
Virtual machine migration for 'zzzzz' failed because configuration data root cannot be changed for a clustered virtual machine. (Virtual machine ID FDBC40ED-634C-4EBD-A645-5CE816B55D13)
Unknown error (0x8005)
Recommended Action
Resolve the host issue and then try the operation again.
Unable to delete cluster resource group dc4e6197-6918-45a4-9a42-63137f792b38 on host xxxxxxxx.edu.com.
Unknown error (0x80338126)
Recommended Action
Use Failover Cluster Management to delete the cluster resource group."
Any ideas?
