HyperV 2016 - Update Cluster Functional Level

[garethEds]

Our hand was forced on Monday when something weird happened to one of our nodes and it decided to dump it's roles onto our second node. It then blue screened.

 

So a decision was taken to push the upgrade to HyperV2016 - and this has gone well. This morning I finished the upgrade of the second server. It is now running 2016/2016 as a cluster and the failover and migration of roles is working really well.

 

Now - how much testing would you do on this before you upgraded the Cluster Functional Level?

 

I still have backups of the roles at the 2012r2 level, but this seems to be the last step.

 

Any advice welcome

I think I waited a week or two, but honestly it was a power shell one liner and didn't cause any issues.
