<p>I am migrating from ingress to gateway on GKE and wondering if there are things I could keep from the old configuration or if I have to start from zero with GW.
Also, I use envoy proxy, do I need a specific one per route?</p>

<p>If your concern is related to the GKE Gateway controller. I recommend checking this <a href="https://cloud.google.com/kubernetes-engine/docs/concepts/gateway-api#comparison_of_ingress_and_gateway" rel="nofollow noreferrer">Comparison of Ingress and Gateway</a>. This explains how Gateway is an evolution of Ingress and it will also show you the differences in configuration of Ingress over Gateway.</p>
<p>For additional information,I also recommend checking this document about <a href="https://cloud.google.com/kubernetes-engine/docs/concepts/gateway-api" rel="nofollow noreferrer">Gateway</a> and <a href="https://cloud.google.com/kubernetes-engine/docs/how-to/deploying-gateways" rel="nofollow noreferrer">Deploying Gateways</a>. For other concern, you may contact <code>gke-gateway-feedback@google.com</code> since this feature is still in the Preview launch stage.</p>
