Downgrading to previous versions
FortiAnalyzer does not provide a full downgrade path. You can downgrade to a previous FortiAnalyzer firmware release via the Web-based Manager or CLI. A system reset is required after the firmware downgrading process has completed.
| All configuration will be lost after downgrading the device, and the hard drives might be formatted automatically. |
| Firmware downgrade is not recommended as it could lead to log data loss. |
To re-initialize a FortiAnalyzer, use the following CLI commands via a console port connection:
execute reset all-settings
execute format {disk | disk-ext4}
