Hi David, I don't know all of your constraints, but a migration architecture that has worked pretty well for our migration from Twisted (WebSockets) + Flask (REST/JSON API) to aiohttp:
1. Avoid to mix the async and sync in the same daemon, to avoid that sync blocks async event loop, even if it's technically possible to mitigate the sync blocking via threads. 2. Put an HTTP reverse proxy behind your application: If you have Flask, you certainly have an Apache or Nginx as reverse proxy to serve static files. In our case, we have used HAProxy. 3. Configure your HTTP reverse proxy to serve between your two daemons, depends on the URI. 4. With that, you can keep your Flask application on 3.6, and use for example aiohttp for WebSockets. 5. If one moment you want to have an all-in-one daemon like us to share easily your business logic code between HTTP and WebSockets, you can easily port endpoint by endpoint your code: With the reverse proxy, it's pretty easy to decide that daemon will serve an HTTP request, and in case of regression, easy to rollback with Flask, the time to fix your portage. 6. The porting has very easy to us, mainly because the aiohttp server API looks like Flask, and aiohttp client API looks like Requests.
