Traefik discovers services through providers and applies router, service, and middleware configuration. An alternative should be tested with your real routing rules and a controlled failure.

Clone a small non-production setup: two services, a path-based route, TLS, authentication middleware, and a redirect. Deploy and remove a backend, rotate a certificate, and observe what users receive while one service is unhealthy. Check forwarded headers, WebSocket or gRPC traffic if used, metrics, and logs. Validate that secret values stay out of configuration and diagnostic output.

Traefik's provider model and middleware reference show the pieces that need mapping. A successful migration includes rollback of both traffic and certificates.
