I tried to install ES 18.104.22.1687-1 on a HP-DL380-G5 running UCM 22.214.171.1240-4. The "cisco-ipt-k9-patch126.96.36.1997-1.tar.gz.sgn" does not show up as an Upgrade File in the OS Administration. I tried with a local DVD and with a FTP Server.
Has anyone successfully installed the ES?
The upgrade is quite urgent since 188.8.131.520-4 is very bugy.
