i upgraded my CCM from 5.0.4 to 5.1.1 the publisher has been upgraded using freeftpd now i'm trying to upgrade subscriber with the same file i used for publisher (file name: cisco-ipt-k9-patch18.104.22.16800-5.tar.gz.sgn about 1.2GB)
the problem is that CCM cannot see the upgrade file (.sgn) in the ftp directory it gives the following error:
The directory was located and searched but no valid options or upgrades were
available. Note, a machine cannot be downgraded so option and upgrade files for previous releases were ignored)).
did any one encounter like this problem?!
