Hi  
By mistake, I have the assumption that 7.6.2 is released on container and so I upgraded thee configurations and applied and ECK accepted the configuration.  
Unfortunately the pods are failing to start and I can't rollback to 7.6.1.  
Can anyone give me a workaround?

**Edit** : if you are experiencing a similar issue please refer to [If you upgraded Elasticsearch to the wrong version](https://www.elastic.co/guide/en/cloud-on-k8s/master/k8s-common-problems.html#k8s-common-problems-version-downgrade) first.

Hi @Ahmad_Al-Masry, that's an identified issue in our Github repository: [Versions existence should be validated · Issue #2455 · elastic/cloud-on-k8s · GitHub](https://github.com/elastic/cloud-on-k8s/issues/2455).

Until we figure out the best way to fix it, I think you can try the following:

- disable the [validation webhook](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-troubleshooting.html#k8s-webhook-troubleshooting) (`kubectl delete validatingwebhookconfiguration elastic-webhook.k8s.elastic.co`)
- apply the manifest with the rollbacked version
- manually delete the Pod that is failing to start in the new unknown version (`kubectl delete pod <pod_name>`)

Once everything is back to its normal state, you can re-create the validating webhoook by reapplying ECK yaml manifests (the one you applied to install ECK).

With [Versions existence should be validated · Issue #2455 · elastic/cloud-on-k8s · GitHub](https://github.com/elastic/cloud-on-k8s/issues/2455) we'll try to figure out a better way to do that.
