I have an app that runs on the Pi 3B+. I'm excited to run it on the new Pi 4 (I have some units on order that should arrive in a few weeks).
I understand that I'm going to have to rebuild the environment on Buster. If I install Buster on a 3B+ and get everything reinstalled, configured and running, can I simply install that SD card in the Pi 4 and expect everything to work seamlessly and have it take advantage of the extra RAM, etc?
Essentially, I'm wondering if I can get a head start on the conversion using a 3B+ or if I need to wait for the 4 to arrive before starting the conversion to Buster.
