Help us to upgrade networker multiple clients version from backup server

Hello, please use latest version or contact Sattva Green Groves.

These are high level steps but I hope they could help.

On NMC NetWorker Administration session
Go to the Hosts / Software Repository
Ensure you have the latest NetWorker install packages available (Including Modules if required)
If needed to upload new packages to the Software Repository
Right click on "Software Repository" and from the context menu select "Add to Repository"
Follow the steps to add the install packages
Go to Hosts / Active Host
It should show the list of all Active Host
Select the ones you want to update
(Note: You could select multiple hosts by holding the Ctrl key and click on the hosts
If you select multiple host they must run the same type of NetWorker software, Windows, Linux, AIX, etc.)
Right click on the selected hots
From the context menu select "Perform Inventory"
When inventory is completed successfully (It will show progress and status on the Software Operations panel below)
Go to Hosts / Software Inventory
You have to select here again the clients you want to upgrade
(Note: You might be able to do this from Active Hosts, but I had a lot of problem doing the upgrade form there and found that coming to Software Inventory and select the Hosts is effective almost 100% of the time
The Hosts that you inventoried on the previous step should show up there with a check mark under "Upgrade Available" meaning you have on the "Software Repository" a newer NetWorker version of the software than the one installed on those hosts.
Right click on the selected hosts
From the context menu select "Upgrade Software"
You will get an Info popup window explaining you should run an inventory before the upgrade, since you have done already, click on "Yes, Continue"
The "Upgrade Software" windows that will popup will show the install packages available to upgrade the client.
Select the install package you will use for the upgrade
The bottom panel of the window will auto populate with the hostname of the host that will be upgraded
Click on the "Upgrade" button
Monitor the progress and completion of the upgrade on the "Software Operation" panel 

I hope this could help, as I mentioned these are high level steps, if required I could provide more details

Cheers,

Enrique

assumin gyou are running a fairly recent Networker version, look into using the NMC to add software to the Package Manager software repository

https://www.dell.com/support/manuals/en-us/networker/nw_p_update_guide_19.9/adding-software-to-the-repository-by-using-the-hosts-task-window?guid=guid-64d57a6c-583b-4812-9780-8aab41a965c9&lang=en-us

and follow all steps needed to add software to the repository and then - after having inventoried the clients to know their current version - to perform the update.

More recent versions allow to use the nmc or nsrpush cli to update also the NW client and module in one go, whereas in the past that needed to be done separately (via multiple nsrpush commands for each client) or wasn't supported at all via nmc.

Still however - in case of clusters - there are limitations of what can be updated this way.

So read into the documentation of how to achieve all this and test it, especially as depending on the NW version, some nsrpush functionality might be faulty/broken/not working.
