If you want a graphical interface to support you/to use nsrpush, go to the NetWorker Admin screen and select the Hosts window. Then follow the steps:
– Create the Software Repository and add the client software version(s) you want to distribute
You better upgrade your server to 9.2.x to because you can add here also the software from the other OS family without
first copying it to an appropriate client (Unix to Windows, for example).
– Run the Software Inventory for your clients
– From the Known Hosts window, select the clients to upgrade and execute the process
Of course, the NetWorker manuals contain more detailed info.
