Hello Samwel Wamui , 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
