Ensure that the new version of Cisco IOS XE software image is already present in the file system of
both the active and standby supervisor engines. Also ensure that appropriate boot parameters
(BOOT string and config-register) are set for the active and standby supervisor engines
Optionally, perform additional tests and commands to determine the current state of peers and
interfaces for later comparison.
