I ran into the issue I was unable to mirror OES11 channels in ZCM, thread is here:

Now I downloaded all the update RPM's manually and try to upload them into ZCM, but I run into the issue I cannot upload delta RPM's.
It just comes back with e.g:
Following file(s) are invalid...


I did upload the base novell-bind RPM first and published the bundle.
The updates mirrored from nu.novell.com have delta RPM's, so it is doable.
Any ideas?
