@jamaicarasta said in Switch from 3.3 to 3.4RC2:
I'm interested in whether the config is fresh or my old one.
Always keep a copy of a version which works, so you can revert to that if some new installations, configuration changes etc. don't run as expected. I understand that you now have a trusted setup with RRF 3.3 - keep a copy of this state before you install 3.4. I even make copies of the SD card before I fiddle around with the config or my macros, not only in the event of a new firmware version.
