    Downgrading

    Downgrading

    In that case downgrade to previous releases of firmware (4.0.x, 4.1.x or 4.2.0 - 4.2.4), you can downgrade directly to any release before the current one without any key being required. The downgrade procedure is similar to the upgrade one as follow:

    • Always back up your system configurations and store in a safe place before downgrading.
    • Note: If you are downgrading to version 4.2.2 or earlier, you must delete all aggregated port settings (go to System > Network Setting > VLAN and Port Mapping on Web UI) before downgrading, otherwise, the system will fail to boot up after downgrading.
    • Log in to FortiWAN as Administrator and go to System > Administrator page.
    • Click Downgrade to start the downgrade procedure.
      • Click Browse to select the old firmware image that you want to downgrade to.
      • Select Upload.
    • Be patient while the firmware is being downgraded. During the downgrade, do not turn off the system, unplug the power or repeatedly click the Submit button.
    • The message “Downgrade succeeded” will appear after the downgrade is completed. Please reboot the system afterward for the firmware to take effect.

    Note: Downgrading from AscenLink is not supported.
