Nginx to Higress Migration

Automate migration from ingress-nginx to Higress in Kubernetes environments.

⚠️ Critical Limitation: Snippet Annotations NOT Supported

Before you begin: Higress does NOT support the following nginx annotations:

• nginx.ingress.kubernetes.io/server-snippet
• nginx.ingress.kubernetes.io/configuration-snippet
• nginx.ingress.kubernetes.io/http-snippet

These annotations will be silently ignored, causing functionality loss!

Pre-migration check (REQUIRED):

kubectl get ingress -A -o yaml | grep -E "snippet" | wc -l

If count > 0, you MUST plan WASM plugin replacements before migration. See Phase 6 for alternatives.
