Firmware best practice: Stay current on patch releases for your current major release.

For more information, see the FortiManager Release Notes on the Fortinet Document Library (https://docs.fortinet.com/), or contact Fortinet Customer Service & Support (https://support.fortinet.com/).
Upgrade FortiManager before upgrading FortiOS, and be sure to maintain release version compatibility at all times.
