Ah, from Gaia R75.47 to Gaia R77.30. Then settings should have been saved, that's not a good thing.
And you did the exact same upgrade (OS versions and hardware) with the exact same method many times previously? I am asking because I am not sure that this method and package is the right one. I didn't do such upgrades for 2200 with similar versions myself, so everything is just as far as I know.
When I go to Upgrade Wizard and fill in your information, I can see that there are two options:
So, one of them is for Legacy CLI upgrade with ISO file, and the second one is for WebUI or SmartUpdate upgrade with tgz package. But you say that you've used "Check_Point_R77.30_T204_Install_and_Upgrade.tgz" which is not in one of these options, there is an ISO file with that name.
All installer ... commands should be connected to CPUSE path, but then the second option shows that the package name should be "Check_Point_R77.30_T204_upg_WEBUI_and_SmartUpdate.Gaia.tgz" and the SK specifically says "Installation of this package using CPUSE is not supported". Also, before some upgrades it is required to update the CPUSE Agent to the latest build.
I see some contradictions here, which could lead to the problems that you had with config loss. As I said, I am not sure about exactly these software and hardware versions, but this is all just from the information from Support Center.
I remember that once I installed a wrong package on an appliance and it worked and everything seemed fine. But all hardware sensors didn't work, they were all just with red status, and SmartView monitor was showing problems because of that too.
