Upgrade Steps Pi3 to Pi4
-
Hi all,
About to upgrade my Pi3B setup to a PI4B 2 gig. Can anyone recommend a good step by step guide to back up all your roms, configs and bios and restore them to the 4?Thanks,

I dont have a guide, but you allready answered your question yourself: just backup all your data and copy it over to the Pi4 with a 4.7 Buster-Image.
You could even do it without backuping, i just got my Pi4 too and am just copying all my stuff from the Pi3B+ -> Pi4B by using the LAN.

The main folders you want to back up are:
/home/pi/RetroPie(ROMs, BIOS files, splash screens)/opt/retropie/configs(configs for RetroArch, EmulationStation, also your scraped game library)/etc/emulationstation(custom themes as well as the systems ES has access to)
The RetroPie documentation has info on how to copy files. WinSCP or Filezilla are probably the easiest programs to use.
Copy those over from the 3B to the 4, and you should be fine. Note: after you flash the image onto your RPi4, you'll need to boot up with it for RetroPie to finish installing, then you can turn it off and start copying.
