Quantum Leap: Mavericks to High Sierra?

[flatlander48]

I’ve been running Mavericks comfortably for some time now with only minor annoyances (occasional system generated restarts upon shutdown, screen does not display after extended non-use, etc.). However, it is time to upgrade to High Sierra. So, some questions that come to mind are:

1. Does the Model Identifier get updated automatically, or does something else need to happen for that?
2. My motherboard has the original firmware from 3 years ago. Does that need to get updated
3. This scares me: https://www.tonymacx86.com/threads/...fter-installation-efi-folder-included.238744/ As my setup is fairly similar, should I expect these kinds of issues?
4. In terms of physical memory, if you had more than 1 memory card, the suggestion was to get the system going on 1 card (8Gb) and then add other cards later. Is that still the case?
5. Does WiFi and Bluetooth work under High Sierra, or is it still out to lunch as before?

Thanks!
