We are currently working with Networker 9.0.3 under Oracle Linux, and we want to apply Cumulative fix 9.0.5, what's the correct procedure to keep all the configuration (Resources, Clients, Devices) to apply it? (we tried to generate it from the Solve, but we don't see anything for updating ... )
Adding to Gautam's reply, follow the Uninstall procedure from NetWorker Installation Guide and do not remove the /nsr folder after you complete the uninstall. Once you get the new cumulative package, follow the install procedure to complete the install/upgrade of Cumulative fix.
PS: Make sure you have the latest bootstrap backup.
