So downgraded my Elasticsearch to 7.17 for me to achieve the all in one deployment with wazuh which was i have been using all along until someone updated the server and in then update the server. I then regenerated the keystore and even used debian to install another elasticsearch 7.17 using debian. but now Elasticsearch is refusing to start. this is the error am getting from logs

Elasticsearch does not support in place downgrades so you can not go from a higher version to a lower version. If you need to do this you need to spin up a new cluster and restore from a snapshot taken from the old version or possibly reindex from remote into the older version cluster from the new one.
