+## Migrating from NGINX Ingress Controller
+
+If you're already using NGINX Ingress Controller and want to migrate to NGINX Gateway Fabric, you can use the ingress2gateway tool to automatically convert your existing Ingress resources to Gateway API resources.
+
+The ingress2gateway tool is a Kubernetes SIG project that helps convert Ingress resources to Gateway API resources. It supports various Ingress controllers, including NGINX Ingress Controller.
+
+{{< call-out "important" >}}
+The ingress2gateway tool is a conversion utility that translates Ingress resources to Gateway API equivalents. It is not a complete end-to-end migration solution. You will need to manually review the converted resources, test functionality, and make additional configuration changes as needed for your specific environment.

+
+### Using ingress2gateway
+
+To convert your existing NGINX Ingress resources to Gateway API resources that work with NGINX Gateway Fabric:
+
+1. Install the ingress2gateway tool following the [installation instructions](https://github.com/kubernetes-sigs/ingress2gateway).
+
+2. Run the conversion command for NGINX provider:
+   ```shell
+   ingress2gateway --providers=nginx --input-file=<your-ingress-file>.yaml > output-file=gateway-api-resources.yaml
+   ```
+
+3. Review the generated Gateway API resources and apply them to your cluster:
+   ```shell
+   kubectl apply -f gateway-api-resources.yaml
+   ```
+
+For detailed information about NGINX-specific features and conversion options, see the [NGINX provider documentation](https://github.com/kubernetes-sigs/ingress2gateway/blob/main/pkg/i2gw/providers/nginx/README.md).
+
+{{< call-out "note" >}}
+After conversion, you may need to adjust some configurations to take advantage of NGINX Gateway Fabric-specific features or to ensure compatibility with your existing setup.
