VMM2016 Maintenance mode/Live migration problem.
I have a cluster of 4 hyper-converged nodes. I'm trying to install the latest CU (KB3197954). The process so far has been
- Start maintenance mode
- install CU
- Stop maintenance mode
- wait for S2D to rebuild
- move on to the next node
This has worked fine for the first 3 nodes. When I tried to put the final node in maintenance mode, I got the following error.
No suitable host is available for migrating the existing highly available virtual machines.
Now I tried to manually migrate a VM. In the Select Host page, I get "Unable to migrate or clone...because the virtualizaton software on the host does not match the version of...source..." (Screen shot attached)
I then tried to Live Migrate a VM in Failover Cluster Manager and it worked fine.

Hi Andy, this is a known issue and we have a fix available for this which will go out in the next Update Rollup (UR2) for VMM.
