I am planning to upgrade our CAS and CAM systems from version 4.6.1 to 4.7.2. The documentation states that "Cisco recommends you do not perform this upgrade procedure over an SSH connection, as the steps necessary to reboot the appliance during the upgrade process will cause your connection to be lost."
Is the only concern with using SSH that you will lose your connection and need to reconnect (and possibly miss some console messages), or is there something in the upgrade that can only be done from a console connection?
My CAS systems are 65 miles apart and being forced to drive between locations will increase the window for a potential outage.
We bumped our CAM and 2 ea. CAS up to 4.7.2 with SSH only, no console access. Not always the best idea (in case for some reason you DO need it) but it can be done completely via SSH for commands and SCP for file transfer.
