The question has been answered. You can even look two threads down and see it does not work for someone. I’m sorry it’s not the answer you want, but the fact is if you update your OS, you run the very big risk of losing access to your unsupported software and projects. Even if someone chimes in and says it works for them, that doesn’t mean you are guaranteed the same result.
If you really must try it, I recommend making a Time Machine backup so you can revert back to what you have if need be.
