TFTP boot firmware upgrade process

Upgrading FortiAuthenticator firmware by interrupting the FortiAuthenticator boot process and installing a firmware image from a TFTP server erases the current FortiAuthenticator configuration and replaces it with factory default settings.

Monitor settings for GUI access

Fortinet recommends setting your monitor to a screen resolution of 1600x1200. This allows for all the objects in the GUI to be viewed properly without the need for scrolling.

Before any firmware upgrade

Save a copy of your FortiAuthenticator configuration before upgrading the firmware. From the administrator dropdown menu in the toolbar, go to Restore/Backup, and click Download Backup File to backup the configuration.

Upgrading from FortiAuthenticator 4.x/5.x/6.0.x

FortiAuthenticator 6.1.2 build 0420 officially supports upgrade from FortiAuthenticator 6.0.4 and higher.

All earlier versions of FortiAuthenticator must first be upgraded to 6.0.4 before upgrading to 6.1.2, otherwise the following message will be displayed: Image validation failed: The firmware image model number is different from the appliance's.

After any firmware upgrade

Clear your browser cache before logging in to the FortiAuthenticator GUI to ensure the pages display properly.
