So n8n 3.0 is in beta and self-hosted is going Docker-only, no more npm/npx installs. Mine has been npx n8n in a tmux session for, uh, a long time. Time to move it.

My plan, tell me what I'm missing:

1. Update to the latest 2.x first and run Settings > Migration Report. It flags workflows using nodes that 3.0 removes (Function, Cron, Item Lists, some old ones).
2. Copy ~/.n8n before touching anything. The encryption key is in there. If the container generates a fresh key, every saved credential turns into garbage. Either mount the old folder or set N8N_ENCRYPTION_KEY to the old value.
3. Full backup, because 2.x to 3.x is one way. No downgrade.
4. Bring up the container on a copy first, check a couple of webhooks still fire (WEBHOOK_URL!), then switch over.

Anyone already done this? Did step 2 go as smoothly as it sounds?
