My organization will not allow ZLM mirroring accross the enterprise as they have other software distribution mechanisms.

How can I update the ZLM servers and agents using a file set? I do have a stand-alone mirror in my development lab, so I can get to the rpms in the pkg-repo directory and distribute them to the target servers using our existing Soft Dist system. Once they are there, how do I install them? Every TID or forum message I read has to do with adding the targets to a catalog - well, I can't do that!!
