Before this update, if you redeployed a full Elasticsearch cluster, it got stuck in an unhealthy state, with one non-data node running and all other data nodes shut down. This happened because new certificates prevented the Elasticsearch Operator from scaling down the non-data nodes of the Elasticsearch cluster. With this update, Elasticsearch Operator can scale all the data and non-data nodes down and then back up again, so they load the new certificates. The Elasticsearch Operator can reach the new nodes after they load the new certificates.
