SUSE told us to use the WEB GUI. However the Web GUI provides only a service pack update procedure for single server (!). It does not scale very well for 600+ servers.
I've not yet tried a service pack upgrade but I already dread it. But even with SUMA 2.1 I've never used system groups or multiple clients in SSM for any upgrade action. I always went client by client. I see nowhere in the GUI any hint about how to upgrade more than one minion at a time. So if you want to use the WebGUI I guess you have to schedule upgrades minion after minion.

You could however use spacecmd (or salt if you like it more) to upgrade multiple server.
