The Gateways use "istio: ingressgateway$SUFFIX" selectors.

1. Install the new gateway in a new namespace.
2. Copy any TLS certificate to the new namespace, and configure the domains.
3. Checking the new gateway work - for example by overriding the IP in /etc/hosts
4. Modify the DNS server to add the A record of the new namespace
5. Check traffic
6. Delete the A record corresponding to the gateway in istio-system
7. Upgrade istio-system, disabling the ingressgateway
