title: Unable to change Azure Function runtime version after deployment
body: <p>I've just deployed several functions to my Azure Function. I have used the 2.0 Function Runtime to create the app but I'm unable to change the version from the previous version I had set (1.0). Is there a way I can change this without deleting the function and starting again?
