I'm in a similar boat. Our project was angularjs (angular 1), and we've been transitioning to React. I don't know Vue, and I don't know your setup, but what we opted for was: 1. Building a foundation in Vue/React. 2. Create an iframe component. 3. Load the angularjs app into the iframe. 4. Build a messaging system to notify the parent app of state changes. 5. Build a system to show/hide the angular app depending on the URL or view. This method worked well for us.
