Hello, I read the instructions about upgrading cluster: [https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html) I have still few questions: Lets say that I have 2 hosts and on every host I installed 3 elasticsearch nodes (Every node have own elasticsearch.yml and init scirpt). How should properly look like upgrade of the cluster? Should I: 1.) Stop shard allocation 2.) Stop 3 nodes of elastic on that host 3.) Upgrade elasticsearch 4.) Start service es1, es2, es3 5.) Wait for status green of cluster. After that should I do the same with second host? ---
