Hi @sandi_pusghiyan ,

At our customers we always extend the existing cluster with a new leg or legs with the target operating system. 

After the data replication old leg or legs are removed from the cluster.

I hope it helps.

Yes. Exactly same way as you install any OS patch. https://www.dynatrace.com/support/help/managed-cluster/operation/apply-operating-system-patches-to-a...

You can also use backup and restore method if you want to do it quickly, I tried it like 3 times and it worked fine.

Thanks,

Hi @islam_zidan,

Keep in mind that in case of backup restore you lose the  user session data (maybe it is important for some clients).
