Reverting to a previous firmware version

FortiGate Firmware

6Select OK.

The FortiGate unit uploads the firmware image file, reverts to the old firmware version, resets the configuration, restarts, and displays the FortiGate login. This process takes a few minutes.

7Log into the web-based manager.

8Go to System > Status and check the Firmware Version to confirm that the firmware is successfully installed.

9Restore your configuration.

For information about restoring your configuration, see the FortiGate Administration Guide.

10Update antivirus and attack definitions.

For information about antivirus and attack definitions, see the FortiGate Administration Guide.

Reverting to a previous firmware version using the CLI

This procedure reverts 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 you can:

•back up the FortiGate unit system configuration using the command execute backup config

•back up the IPS custom signatures using the command execute backup ipsuserdefsig

•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 your 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, use the procedure o 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-nowto 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.

To use the following procedure, you must have a TFTP server the FortiGate unit can connect to.

To revert to a previous firmware version using the CLI

1Make sure the TFTP server is running.

2Copy the firmware image file to the root directory of the TFTP server.

3Log into the FortiGate CLI.
