Reverting to a previous firmware version

The FortiGate unit uploads the firmware image file, upgrades to the new firmware version, and restarts. This process takes a few minutes.

9Update antivirus and attack definitions (see the FortiGate Administration Guide), or from the CLI, enter:

execute update-now

Reverting to a previous firmware version

Use the following procedures to revert your FortiGate unit to a previous firmware version.

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.

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.

2Log into the FortiGate web-based manager.

3Go to System > Status.

4Under System Information > Firmware Version, select Update.

5Type the path and filename of the firmware image file, or select Browse and locate the file.
