All Pilot related configuration should be removed from the static configuration.
### Kubernetes Ingress Path Matching
In v3, the Kubernetes Ingress default path matching does not support regexes anymore.
#### Remediation
Two levels of remediation are possible:
- Interpret the default path matcher `PathPrefix` with v2 syntax.
This can done globally for all routers with the [static configuration](#configure-the-default-syntax-in-static-configuration) or on a per-router basis by using the [traefik.ingress.kubernetes.io/router.rulesyntax](../routing/providers/kubernetes-ingress.md#annotations) annotation.
- Adapt the path regex to be compatible with the Go regex syntax and change the default path matcher to use the `PathRegexp` matcher with the [`traefik.ingress.kubernetes.io/router.pathmatcher`](../routing/providers/kubernetes-ingress.md#annotations) annotation.
