Just checking to see if anyone else has encountered this problem. I'm trying to upgrade to 6.0(1a) from the base 6.0 image. I downloaded the files from CCO and combined them as per the directions. I then go to the upgrade page on the gui and point it to my SFTP server. The file goes through the downloading counter and reaches all the way through the file (about 2.4 gigs). Once it's done downloading, instead of going through the checksum, it just brings me back to the download page (where you select whether to use a local or remote SFTP location). I've tried several methods to get around this and nothing has worked. Every time it finishes downloading the file, it just reloads the main install/upgrade page. If anyone has any suggestions, I would appreciate it.
