Firmware downgrade
Downgrading from 7.0.1 to 5.x.x, 6.0.x, or 6.4.x release
Downgrading the firmware to an earlier version is not recommended. The downgrade process may cause the FortiVoice system to remove parts of the configuration that are invalid for that earlier version. In some cases, you may lose all call data and configurations. Before downgrading, contact Fortinet Customer Service and Support first. |
If you do need to downgrade, follow these steps:
- In the FortiVoice console, use the G option in the bootloader to reburn the image.
- Type exec factory reset.
- Restore the configuration.
