I'm trying to do the upgrade using just the .bin files as we only use CLI management tools. I've copied the new 12.2 .bin file onto all 5 switches but as the "boot system switch all" command isn't supported on the current 12.1 image I'm unable to set the boot variable on any of the member switches, only on the master.
I can session onto the members but can't use config mode. I'd prefer to keep the old IOS on each switch as a fallback.
Is it possible to set the boot variable on member switches on 12.1(19)EA1c. If so, how?
