Validating that the node pool meets the requirements for upgrading.\n2. Applying migration labels and creating the admission webhook `ValidatingWebhookConfiguration` to prevent your Knative serving resources from being deleted in the following namespaces:\n - `knative-serving`\n - `cloud-run-system`\n - `gke-system`\n3. Uninstalling the \"*GKE add-on*\", including removing the\n related manager labels from your Knative serving resources.\n\n Note that this process can run for more than 10 minutes.\n4. Adding the `appdevexperience-operator` annotations.\n\n5. Removing the stale `cloudrun.operator.run.cloud.google.com`\n resource that is not used with fleets.\n\n| **Note:** While the traffic to your services remain unaffected, the GKE control plane (\"*master*\") node is updated and therefore, becomes temporarily unavailable during the process. Any operations that require access to the GKE control plane such as Kubernetes resource operations like delete, update, or create will not occur until the update completes.\n\nUninstall the Knative serving GKE add-on\n----------------------------------------\n\nIn this section, the [migration script](/kubernetes-engine/enterprise/knative-serving/docs/install/on-gcp/upgrade/prepare) is used to\nuninstall the \"*GKE add-on*\".\n\n1. Run the following command to start the migration script:\n\n ./migration-addon.sh --command uninstall-cloudrun-addon\n\n2. In the terminal, the migration script prompts you for your confirmation to\n perform each action. Enter `y` to begin the process and also to continue at\n each prompt.\n\n The prompts during the process of uninstalling the\n \"*GKE add-on*\" look similar to the following: \n\n In this process, the script performs the following:\n 1.

Run the following command to start the migration script:\n\n ./migration-addon.sh --command rollback-uninstall-cloudrun-addon\n\n2. In the terminal, the migration script prompts you for your confirmation to\n perform each action.
