Covers why kgateway was chosen over alternatives (Envoy Gateway, Cilium, Traefik, nginx Gateway Fabric), how to use the ingress2gateway translation tool, and how to achieve zero-downtime cutover via weighted DNS with external-dns. Also details behavioral differences to expect: WebSocket upgrade requirements, upstream connection pooling issues, and rate limiting differences. Includes operational lessons around ArgoCD sync ordering, cert-manager namespace topology, and running the controller at multiple replicas. ## Full article daily.dev links to this article rather than hosting it.
