Testing a new firmware image before installing it
You can test a new firmware image by installing the firmware image from a system reboot and saving it to system memory. After completing this procedure the FortiGate unit operates using the new firmware image with the current configuration. This new firmware image is not permanently installed. The next time the FortiGate unit restarts, it operates with the originally installed firmware image using the current configuration. If the new firmware image operates successfully, you can install it permanently using the procedure “Upgrading to a new firmware version” on page 95.
