Is it safe to modify the "OperatingSystem" and "OperatingSystemVersion" attribute manually on cluster name object (CNO)

I have migrated my Hyper-V nodes from Windows Server 2012 R2 cluster to Windows Server 2016 but in AD still my CNO name is looking "Windows Server 2012 R2" in OS field. I tried to modify it but it is not editable. However, looks I can modify this value directly using attribute editor.

So may I know it is safe to modify directly CNO attribute "OperatingSystem" and "OperatingSystemVersion"?

    Hi,

    I didn't find any official doc mentioned the "OperatingSystem" and "OperatingSystemVersion" attributes. Just to be on the safe side, it is recommended not to modify it manually. Have you run Update-ClusterFunctionLevel after upgrading all the nodes to Windows Server 2016? If not, you can run it from powershell and see if those attributes are updated.

    Best Regards,

    yes, I had done Update-ClusterFunctionLevel but it did not update. I updated those attribute manually and so far did not get any issues. I think it is safe to update those attribute.

    Well, I guess those two attributes are information so updating information should not cause any issues. I will observe few more days.
