Upgrading the firmware

Periodically, Fortinet issues firmware upgrades that fix known issues, add new features and functionality, and generally improve your FortiAuthenticator experience. See Firmware upgrade for more information.

Before proceeding to upgrade your system, Fortinet recommends you back up your configuration. Please follow the procedure detailed in Backing up and restoring the configuration.

To upgrade the firmware, you must first register your FortiAuthenticator with Fortinet. See Registering your Fortinet product for more information.

To upgrade FortiAuthenticator firmware from the GUI:

1. Download the latest firmware to your local computer from the Fortinet Support website.
2. Go to System > Administration > Firmware Upgrade.
3. Select Upload a file and locate the firmware image on your local computer.
4. Select OK.
   The firmware image uploads from your local computer to the FortiAuthenticator device, which will then reboot. For a short period of time during this reboot, the FortiAuthenticator device is offline and unavailable for authentication.

   For ftp servers:

   execute restore image ftp <filename> <ftp_ipv4>
