Upgrading the firmware - web-based manager

Installing firmware replaces your 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.

Always remember to back up your configuration before making any changes to the firmware.
To upgrade the firmware
  1. Log into the web-based manager as the admin administrative user.
  2. Go to System > Dashboard > Status and locate the System Information widget.
  3. Beside Firmware Version, select Update.
  4. Type the path and filename of the firmware image file, or select Browse and locate the file.
  5. Select OK.

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