This example shows how to use issu changeversion with the at command option to schedule an ISSU
upgrade procedure to automatically start at the specified time. This example specifies that the ISSU
upgrade should be started at 16:30 (24 hour format). The show issu state detail and show redundancy
command output is included to show the supervisor state before and after the issu changeversion
command was entered.
