The ISSU process has completed. At this stage, any further Cisco IOS XE software version upgrade or
downgrade will require that a new ISSU process be invoked.
Using changeversion to Automate an ISSU Upgrade
This task describes how to use the issu changeversion command to perform a one step ISSU upgrade.
Prerequisites
• 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.
