Changing the asp.net application to use async little by little

Question

We have an asp.net application, it does not use asynchronous or parallel methods (with the exception of some owin middleware).

I want to start using the asynchronous version of some methods using the async-wait syntax.

I know there is a danger in mixing async and sync operations, as this can cause deadlocks.

It is not possible to rewrite the entire application in one go.

Where do i start? safe way to do this is to make controller actions asynchronous and work my way down? or vice versa?

Are there any explicit warning signs that I can observe along the way like: "never use the sync method to call the async method, but fine to synchronize the asynchronous call"
