I'd like to do my CUCM 6.x to 7.x upgrade remotely. I have the upgrade disc (CUCM upgrade from 6.x to 7.1(3b)); however, if I try to do the upgrade from ftp or sFTP, no valid upgrade files can be found. If I place the disc into the CUCM server, it is found immediately. I've referenced the below doc and tried to setup my sFTP server via / and let it scan the disc (I tell my FTP server to include sub-directories), but it looks like Windows or the sFTP software won't let CUCM CWD (as seen on sniffer). If I try to search the disc for UCSInstall_UCOS_7.1.3, it can't be found....I assume it's TARed, or GZ and that is why I can't find it, but when I look for TAR or GZ files, I don't see anything that looks like the install file, and therefore, where exactly I should point my FTP server to. In summary, (since the Cisco doc doesn' say where the path is on the disc), where should I point my FTP server directory to, in order to upgrade remotely?
