Downgrading to Previous Versions of Firmware

Downgrading to previous versions of firmware

FortiAnalyzer does not provide a full downgrade path. You can downgrade to a previous firmware release via the GUI or CLI, but doing so results in configuration loss. A system reset is required after the firmware downgrading process has completed. To reset the system, use the following CLI commands via a console port connection:

execute reset all-settings
execute format {disk | disk-ext4}
