**Upgrading from < v3.4.0**
Chart 3.4.0 deprecates support for Helm 2 and also removes the creation of the `gatekeeper-system` Namespace from within the chart. This follows Helm 3 Best Practices.

Option 1:
A simple way to upgrade is to uninstall first and re-install with 3.4.0 or greater.

A simple way to upgrade is to uninstall first and re-install with 3.4.0 or greater.

```console
$ helm uninstall gatekeeper
$ helm install -n gatekeeper-system [RELEASE_NAME] gatekeeper/gatekeeper --create-namespace

```

Option 2:
Option 2:
Run the `helm_migrate.sh` script before installing the 3.4.0 or greater chart. This will remove the Helm secret for the original release, while keeping all of the resources. It then updates the annotations of the resources so that the new chart can import and manage them.

Realized I need to change the gatekeeper-webhook-service port.
Instead of changing this using kustomize i changed this in the config file instead and use the name.

Thanks to this it will also simplify the GKE usage since they won't have to update the service since we are using the port name instead of the port number, I have updated the docs accordingly.
