Verifying the ISSU State Before Beginning the ISSU Process

Ensure that the active and standby supervisor engines are up and in ISSU Init state and that both
supervisor engines are running the same current image.
The following example displays the ISSU state before the process begins:
Switch# show issu state detail
The new version of the Cisco IOS XE software must be present on both of the supervisor engines. The
directory information displayed for each of the supervisor engines shows that the new version is present.
Switch# dir bootflash:
Directory of bootflash:/
