    Did it show the serial number before the upgrade?

    Tried a smc and nvram reset?

    What does it mean clean install?
    I installed on the App Store.

    By clean install, I mean erasing the drive before installing Mojave.

    If you can enter internet recovery, you can install Mojave over wifi. If not, you will need to use another Mac to create a usb installer.

    I changed I/O board.
    Is this possible causing the problem?

    You should run a factory program, I just don't know which one.

    Changing the MagSafe i/o board should not cause this problem. I have changed the board in several airs without any issues.

    What about using an earlier OS such as Sierra or High Sierra?

    I have read that, for unknown reasons, some Macs might lose the serial number. That seems unlikely, when the serial is burned into the bootrom of your Mac. But, if it is missing, that's all you need to know.
    You can try to re-apply the serial number, by using Apple's tool named "Blank Board serializer"
    That software is used by Apple whenever logic boards are replaced, as the replacement board serial number is blank
    There's some information on this web page - http://rogersm.net/icloud-problems-mountain-lion-serial-number

    This solution works the old Mac, and not working new.

    Are you near an Apple store? That may be where you need to go to get this sorted out.

    I think so, this is the easy way and expensive.

    Did they tell you how they got the serial number to appear?

    There is a special software for them to write back.
