We have over 600 sles based servers and we need to update them all within a period of one month. I'm looking for a solution where I can create static groups with a bunch of servers, i.e. group1, group2 and so on. This is the easiest step.
Now we plan to schedule automatic systemupdates during nighttime: Group1 update at 02am, group2 at 4am and so on. Additional we need to run Pre- and Postscripts with the schedule. Where I find a function like this in the WebGui?

It's just patching - not SP-Migration!

Anyone an idea?
