## Migrate 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](https://github.com/kubernetes-sigs/ingress2gateway) tool to automatically convert your existing Ingress resources to Gateway API resources.

The ingress2gateway tool is a Kubernetes SIG project for converting Ingress resources to Gateway API resources. It supports multiple Ingress providers, 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.

### Use ingress2gateway

To convert your existing NGINX Ingress resources to Gateway API resources that work with NGINX Gateway Fabric:


First, [install the ingress2gateway tool](https://github.com/kubernetes-sigs/ingress2gateway?tab=readme-ov-file#installation).

Then run the conversion command for the NGINX provider:

```shell
ingress2gateway print --providers=nginx --input-file=<your-ingress-file> > gateway-api-resources.yaml
```

This tool will analyze your Ingress resources from the input file and output the equivalent Gateway API resources to a file named `gateway-api-resources.yaml`. Finally, review the generated Gateway API resources in the output file 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).

# Migrate 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](https://github.com/kubernetes-sigs/ingress2gateway) tool to automatically convert your existing Ingress resources to Gateway API resources.

## Why migrate?

The [Gateway API](https://gateway-api.sigs.k8s.io/) is the next-generation Kubernetes networking API that builds on the limitations of Ingress. Compared to Ingress, Gateway API provides:

- **Role-oriented resources**: Distinct resources for infrastructure providers, cluster operators, and application developers, enabling [separation of concerns](https://gateway-api.sigs.k8s.io/concepts/security-model/#role-oriented-resources).
- **More expressive routing**: Support for [advanced traffic management](https://gateway-api.sigs.k8s.io/concepts/api-overview/#routes) such as path-based and header-based routing, traffic splitting, and TLS configuration.
- **Standardization and portability**: A Kubernetes [community standard](https://gateway-api.sigs.k8s.io/) supported by multiple vendors, ensuring consistent behavior across implementations.
- **Extensibility**: Built on Kubernetes [CRD extensibility](https://gateway-api.sigs.k8s.io/concepts/design-principles/#extensibility) to support new capabilities without breaking the core API.

Migrating to Gateway API with NGINX Gateway Fabric helps future-proof your Kubernetes networking stack, provide a standardized API across implementations, and unlock advanced traffic management features.
