In a cluster environment, it is recommended to upgrade the cluster in the following order:
Upgrade a unit after the previous one fully boots up. After upgrade, it is highly recommended to setup a cluster level failover IP set, so the failover between Master and Primary Slave can occur smoothly.
When upgrading from 3.1.0 or later and the new firmware is ready, you will see a blinking New firmware available link on the dashboard. Click the link and you will be redirected to a page where you can either choose to download and install an available firmware or manually upload a new firmware.
Upgrading FortiSandbox firmware consists of the following steps:
- Download the firmware image from the Fortinet Customer Service & Support portal.
- When upgrading via the CLI, put the firmware image on a host that supports file copy with the SCP or FTP command. The FortiSandbox must be able to access the SCP or FTP server.
In a console window, enter the following command string to download and install the firmware image:
fw-upgrade -b -s<SCP/FTP server IP address> -u<user name> -t<ftp|scp> -f<file path>
- When upgrading via the Web UI, go to System > Dashboard . In the System Information widget, click the Update link next to Firmware Version. The Firmware Upgrade page is displayed. Browse to the firmware image on the management computer and select the Submit button.
- Microsoft Windows Sandbox VMs must be activated against the Microsoft activation server if they have not been already. This is done automatically after a system reboot. To ensure the activation is successful, port3 of the system must be able to access the Internet and the DNS servers should be able to resolve the Microsoft activation servers.
Downgrading to previous firmware versions is not supported.
