I would like to apply a service update on my cluster to solve a specific issue that is a known bug with our existing 9.1.1(a). I will be upgrading to 9.1(2)SU2a and a newer phone firmware will be on the tftp servers post upgrade. I would like to prevent the phones from upgrading if possible. I have 1 publisher node, 2 sub nodes for TFTP, and 2 sub nodes for registering phones. My idea is to switch versions on the publisher and TFTP nodes followed by manually replacing the phone firmware files on the TFTP server back to the old files. After that, I will switch versions on the phone registration nodes which is normally where the phones would upgrade firmware. Since I had manually replaced the fw files back to what they were pre-upgrade I am thinking the phones will go through a reboot but they won't upgrade.
Just trying to figure out if I am on the right track and whether or not my idea is valid. If there is a better way to accomplish please let me know and thanks.
