I recently upgraded my UTM 9 hardware from an old Core 2 Duo to an i5, and the backup/restore process seemed to go off without a hitch until I went into testing. Even though the NAT rules were in place and showing as active, the system was rejecting traffic that was supposed to be NAT'd. After several troubleshooting steps like recreating the rules to force the system to reload them, turning off rules, and the proposed steps of rebooting the system 3 times, I ended up rebuilding and starting from scratch.
Naturally that isn't the way things should happen, but I am just curious if there are other ways to check for such problems and possibly fix them in place? If I had a more complex environment, I probably would have put the old system back in place and just hoped it would stay running.
