Then you could create Ingress objects.\n\nIn version 1.8, you do not create a Gateway object. You can create Ingress\nobjects as usual.\n\nTo upgrade to 1.8 from a 1.7 user cluster that has ingress enabled, you must first\nrun a tool that converts the old ingress mechanism to the new one.\n\nTo check to see whether you need to run the tool, attempt to\n[upgrade the user cluster](/anthos/clusters/docs/on-prem/1.8/how-to/upgrading#upgrade_user_cluster):\n\n```\ngkectl upgrade cluster --kubeconfig ADMIN_CLUSTER_KUBECONFIG --config USER_CLUSTER_CONFIG\n```\n\nIf you see the following error, then you need to run the tool:\n\n```\n- Validation Category: Ingress\n Running validation check for \"User cluster Ingress\"... /\n - [FAILURE] User cluster Ingress: detected usage of unsupported Ingress, ...\n```\n\nHere are the steps:\n\n1. Follow the instructions for using the\n [migration tool](https://github.com/istio-ecosystem/istio-ingress-migrate#usage).\n\n2. After resolving any issues remember to annotate the Gateway object.\n\n3. Continue with the regular upgrade process.\n\nIf your cluster has ingress enabled, skipping the migration step might result in\ntraffic disruption for all services using ingress.\n\nWhat's next\n-----------\n\n[Create a Service and an Ingress](/anthos/clusters/docs/on-prem/1.8/how-to/create-service-ingress)"]]
