Firmware image checksums

The MD5 checksums for all Fortinet software and firmware releases are available at the Fortinet Customer Service & Support portal located at https://support.fortinet.com.

Upgrading cluster environments

In a cluster environment, it is recommended to upgrade the cluster in the following order:

1. Worker devices
2. Secondary devices
3. Primary devices

Upgrade a unit after the previous one fully boots up. Before upgrading, it is highly recommended you set up a cluster level failover IP set, so the failover between Primary and Secondary devices can occur smoothly.

Upgrade procedure

Upgrading FortiSandbox firmware consists of the following steps:

1. Download the firmware image from the Fortinet Customer Service & Support portal.
2. 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>

3. 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.
4. 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

Downgrading to previous firmware versions is not supported.

FortiSandbox VM firmware

As with all VM upgrades, take a snapshot or make a checkpoint before upgrading.

Fortinet provides FortiSandbox VM firmware images for VMware ESXi, Nutanix, and Kernel Virtual Machine (KVM) virtualization environments.

Firmware image for Hyper-V is not available due to upgrade issue specific to the Hyper-V environment.

For more information, see the VM Installation Guide in the Fortinet Document Library.
