A rescue image is a snapshot of your current system that is automatically created during the
software upgrade process. The rescue image represents the starting version of the
ExtremeCloud IQ
Controller upgrade and its configuration state. If necessary,
you can use the rescue image to revert back to the controller's previous version and
state after a software upgrade.
Note
It is a best practice to always create a rescue
image.
By default, ExtremeCloud IQ
Controller saves one rescue image. The intent is to
offer you a means of reverting back to the last software version and configuration
state before the upgrade.
