OES11sp1 > Use OES11 repositories

Hi,

We use ZLM to update and maintain patches for our SLES(10 and 11) and OES(2 and 11) servers.
Novell(SuSE) changed the way it patches servers in OES11sp2, https://www.suse.com/support/kb/doc.php?id=7010225

My question is for OES11sp1. Do I need to assign OES11 and OES11sp1 channels to my OES11sp1 server, or just OES11sp1 channels?
I guess both as there don't seem to be any updates in the OES11sp1 channels at the moment.

Thanks,
Hein
