Switching to the backup firmware image
Use this procedure to switch the FortiGate unit to operating with a backup firmware
image that you previously installed. When you switch the FortiGate unit to the backup
firmware image, the FortiGate unit operates using the configuration that was saved
with that firmware image.
If you install a new backup image from a reboot, the configuration saved with this
firmware image is the factory default configuration. If you use the procedure
“Switching back to the default firmware image” on page 45 to switch to a backup
firmware image that was previously running as the default firmware image, the
configuration saved with this firmware image is restored.

execute reboot
