Hi Jonathan, Did you try first to change the compatibility of all clusters and then change the data center's compatibility?

Hi Jonathon, it's difficult to say as it's so long since I ran that version. I notice on 4.2 nodes that they have Cluster Compatibility Version: 3.6,4.0,4.1,4.2 Would it to be better to update the hosts first?
