+Each version of the Flux `Alert` and `Receiver` CRDs must be patched, so the JSON6902 patch statement should be repeated with a different `versions` index.
+
+The list of CRD versions on the cluster can be queried with Kubectl.
+For example, to use `jq` to get the count of versions for the `Alert` CRD:
+```sh
+kubectl get -ojson crd alerts.notification.toolkit.fluxcd.io | jq '.spec.versions | length'
+```
