Hello,
I'm looking for a way to upgrade the boot version of a few CBS220 switches I have deployed. The vast majority of switches I have are running boot version 10.0.0.17, however I noticed a few are running 10.0.0.14. All switches are on the same active firmware version, with the only difference being boot version. However I am unable to find a .rfb file or anything similar that would allow me to update the boot version. I am only able to find the .bin firmware files on the Cisco Software portal.
Am I missing something or is it not possible to upgrade boot version on CBS220 switches?
Thanks!
