Guidelines
A firmware upgrade performed with the boot image command retains current
configuration data, allowing the appliance to be restored (rolled back) to a known,
stable state if necessary. The previous firmware image and associated configuration
data is referred to as the secondary install; the newly installed firmware image and
associated configuration data is referred to as the primary install.
You can use the boot switch command to toggle between the newly installed and
previously active firmware versions.
Configuration edits made to a selected install are local and do not transition
during rollback. It is possible to issue the boot switch command twice, returning
the appliance to the newly installed version.
While, you can use the boot delete command to delete the secondary install, keep
in mind that its deletion will prevent firmware rollback as provided by the boot
switch command. Consequently, deletion of the secondary install is not
recommended.
