Reverting to a previous firmware version using the web-based manager

The following procedures 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 information, see the FortiGate Administration Guide.

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.

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.
