I would like to upgrade from version Arduino 1.8.15 (Windows Store 126.96.36.199) to the new Arduino 2.0 but I’m very scared as every upgrade bring many differences and troubles. Someone can help me to solve this doubt. If I upgrade to the new Arduino IDE 2.0 it’s possible that some of many exercises done with ESP32 wont’ run more ?.
That is every libraries I’ve installed will be used from this new version of Arduino IDE ?
If you install Arduino 2.0 in a different path than your other Arduino installation, everything should be fine —this way both versions won’t conflict.
You have to keep in mind, that if you want to start with Arduino 2.0, it is as if you’re starting from zero (this is, you need to install the ESP32 boards add-on and all the other libraries that you have installed in your older version and want to use with this new version.
I hope this answers your question.
