nginx-to-higress-migration

To migrate nginx Ingress configurations to Higress, you can use an automated workflow that preserves routing, TLS, and security semantics. It analyzes Ingress resources and nginx annotations, validates compatibility in a Kind cluster, and performs a safe cutover.

Yes, you can convert unsupported nginx snippet-based features into WASM plugins during the Higress migration. The migration process includes optional WASM plugin generation to replicate advanced snippet functionality, validated using a Kind-based testing environment.

The best way to check nginx to Higress compatibility is by running an automated pre-migration analysis script. It evaluates existing Ingress resources and nginx.kubernetes.io annotations, allowing you to validate configurations in a Kind cluster before executing the production cutover.

Yes, you need Helm for installing Higress with the same ingressClass and Kind for local cluster validation. These tools enable parallel deployment and end-to-end compatibility testing to ensure a safe, auditable transition from ingress-nginx.

The Higress migration handles nginx ConfigMaps and Ingress resources by applying automated compatibility analysis. It preserves your existing routing and security semantics while translating nginx-specific configurations into the corresponding Higress format.

A key limitation of migrating from ingress-nginx to Higress involves compatibility gaps from snippet-based features. Unsupported snippets require manual intervention or optional WASM plugin generation to preserve business logic during the cutover transition.
