Physical Cell Manager - Entire system Restore from Backup ISO Options

Hi All

I have a Data protector 10.91 Cell Manager residing on a Physical Server 2012 R2 Server.

We are in the process of performing in place Operating System Upgrades to many of our servers currently > 2012 R2 to 2019.

Our IDB is fairly large and I am trying to cover my back as much as possible if anything were to go wrong and I needed to perform a full OS restore.


I was hoping to perform (I think) a full system ADR backup of our Cell Manager which as I understand would create a bootable ISO I could use to recreate and restore our Cell Manager back to its original 2012 R2 state if anything were to go wrong.

Would this be the best option for what we are trying to achieve or would a better approach we advised.


I would appreciate any comments or insight.

Many thanks
