XG210 Firmware Update SFOS 17.5.16 MR-16-Build830 to SFOS 18.5.1 MR-1-Build326

Hi Everyone!

We are trying to update our XG210 firewall firmware SFOS 17.5.16 MR-16-Build830 version to SFOS 18.5.1 MR-1-Build326 version. Based on the listed version numbers, this update should not fail. But after the update, we see that the IP settings have completely changed for WAN and LAN. Also, when we connect the computer via LAN, we see that no configuration is saved on the device.

It's like the device has been restored to factory settings in the new version. When I try to restore the backup from the previous version (SFOS 17.5.16 MR-16-Build830), the new version (SFOS 18.5.1 MR-1-Build326) the same situation is seen in the new version.

According to the release notes, I should be able to update between the relevant versions without any problems.

Am I missing something? Could you help me?

P.S: By the way, since I could not solve the problem, I booted the device from the old version. You can see the screenshot attached.
