Sophos XG 310 not upgrading firmware from 17.5

It keeps reversing back to 17.5 when we upgrade to 19.

  • Hi,

    you need to go to v18 first or do a fresh install from the iso. Be careful because the backups might not restore.

  • Hello ,

    Thank you for reaching out to the community, please refer the guide below:

    Migration versions

    We strongly recommend that you migrate only to the approved versions listed in the following table. If you try to migrate to other versions, Sophos Firewall shows an alert asking you to confirm the migration before it restarts. If you confirm the migration, Sophos Firewall restarts with the factory configuration, and you lose your current configuration.

    You cannot upgrade from SFOS 17.5 to SFOS 19.0 MR1.
    The right migration path from v17.5 will be to v18.06 MR-6


    Thanks & Regards,
