To upgrade the system from KerOS version 4.3.3 to KerOS version 5.x the use of a liveburner is MANDATORY. Two possibilities are available:
- Upgrade with a custom liveburner. It allows to keep some elements like gateway configuration. To use a custom liveburner, please refer to the dedicated page: Major version upgrade with a custom liveburner.
- Upgrade with a regular liveburner (erasing the whole partition to reinstall the firmware)

Installation of SPN firmware from version 5.X is not possible. You will have to downgrade from 5.X to 4.3.3-2 (available bellow).

The firmware is released in two formats: KerOS and Liveburner.

KerOS : Update the Firmware
To update the firmware from v5.x, the regular update procedure can be used. See system upgrade page.
