Verifying the ISSU State Before Beginning the ISSU Process
Ensure that both the supervisor engines are configured to auto-boot, and that they have currently been
booted from the pre-upgrade image residing on the local file system. This is verified by the values of the
BOOT variable and the configuration register (refer to the sample output of show redundancy command
in the previous section).
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:
