Use the web-based manager or CLI procedure to revert to a previous firmware
version. This procedure reverts the FortiGate unit to its factory default
configuration.
Downgrading the firmware to a previous version will revert the FortiGate unit to its
factory default configuration and deletes IPS custom signatures, web content lists,
email filtering lists, and changes to replacement messages.
Before beginning this procedure, it is recommended that you:
• back up the FortiGate unit configuration
• back up the IPS custom signatures
• back up web content and email filtering lists
For more information, see the
If you are reverting to a previous FortiOS version (for example, reverting from
FortiOS v3.0 to FortiOS v2.80), you might not be able to restore the previous
configuration from the backup configuration file.
Note: Installing firmware replaces the current antivirus and attack definitions, along with
the definitions included with the firmware release you are installing. After you install new
firmware, make sure that antivirus and attack definitions are up to date. For details, see the
FortiGate Administration Guide. You can also use the CLI command execute
update-now to update the antivirus and attack definitions.
Note: To use this procedure, you must log in using the admin administrator account, or an
administrator account that has system configuration read and write privileges.
