Software

  • 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)
