Upgrading the FortiManager firmware for an operating cluster
You can upgrade the firmware of an operating FortiManager cluster in the same way as upgrading the firmware of a standalone FortiManager unit.
To do the upgrade, connect to the primary unit GUI or CLI to upgrade the firmware. Similar to upgrading the firmware of a standalone FortiManager unit, normal FortiManager operations are temporarily interrupted while the cluster firmware upgrades. Because of this interruption, you should upgrade cluster firmware during a maintenance period.
To upgrade FortiManager HA cluster firmware:
- Log into the primary unit GUI.
- Upgrade the primary unit firmware.
The firmware is sent to all backup units, and then all units (primary and backup) are rebooted.
See the FortiManager Release Notes and FortiManager Upgrade Guide in the Fortinet Document Library for more information.

You might not be able to connect to the FortiManager GUI until the upgrade synchronization process is complete. During the upgrade, using SSH or telnet to connect to the CLI might be slow. If necessary, use the console to connect to the CLI. |
