You must upgrade to 6.2.10-45 before you can upgrade to versions 6.2.18 or later.\n\n* **ValidatingWebhookConfiguration**\n\n  This release uses a new `ValidatingWebhookConfiguration` resource to replace the `redb-admission` webhook resource. To use releases 6.4.2-4 or later, delete the old webhook resource and apply the new file. See [upgrade Redis cluster](https://redis.io/docs/latest/operate/kubernetes/upgrade/upgrade-redis-cluster#reapply-webhook) for instructions."
