Migration Strategies

1. Drain

Stop accepting new connections on v1. Wait for all v1 sessions to end (or timeout). Then kill v1.

2. Force Up

If a user is on v1, clear their conversational context (reset state) and start them fresh on v2. (Annoying for user, easiest for dev).

3. Map

Write a StateMapper function that translates v1 state to v2 state and seamlessly transfers the user. (Hardest, best UX).
