upgrade xg 310 show message box "this firmware will replace the non-avtive firmware image on your device.

Hi thanong bori,

Thank you for reaching out to the Community! 

You can see a maximum of two firmware versions under Firmware. One of them is the active version. The inactive version is one of the following:

• Previous version: When you change the firmware version of XG Firewall, the previous version is retained to allow you to roll back. If you roll back, configuration changes made after the change are lost because changing the firmware also updates XG Firewall with the configuration that corresponds to the new firmware version.
• Uploaded version: You uploaded a version compatible with the active version. This can be a version later or earlier than the active version.

You can only move (upgrade, downgrade, or roll back) XG Firewall to an inactive version that's compatible with the active version.

You will see this pop up when you try to upload the compatible firmware, this process will replace the non-active firmware, and the newly uploaded firmware will be available that you can boot the firewall with.

Please check out the following document for more information: https://docs.sophos.com/nsg/sophos-firewall/18.0/Help/en-us/webhelp/onlinehelp/nsg/sfos/concepts/BackupsFirmware.html

Thanks,

This message is from uploading / replacement of a firmware image only.

Maybe thats also the message, when you click the download link because it want's to override the inactive firmware image

Do firmware version 18 support Xg 310 ?

Can I perform the upgrade at all?
