Instead of upgrading or downgrading each managed device manually, you can change device firmware through your FortiManager unit.

FortiManager units can store and install FortiGate, FortiCarrier and FortiManager firmware images. FortiManager units can receive local copies of firmware images by either downloading these images from the Fortinet Distribution Network (FDN) or by accepting firmware images that you upload from your management computer.

If you are using the FortiManager unit to download firmware images from the FDN, FortiManager units first validate device licenses, including each member of high availability (HA) clusters. The FDN validates support contracts and provides a list of currently available firmware images. For devices with valid support contracts, you can download new firmware images from the FDN, including release notes.

After firmware images have been either downloaded from the FDN or imported to the firmware list, you can either schedule or immediately upgrade/downgrade a device or group’s firmware.

Firmware versions and maintenance releases do not always contain the same configuration options and because these options are different, you may need to configure the device or group and resynchronize its configuration after changing a device or group’s firmware.
