* DO NOT follow the [https://www.elastic.co/guide/en/elastic-stack/6.8/upgrading-elastic-stack.html upgrade instructions]. Migration Assistant does not work for 5.6 in testing.
* DO NOT prepare a 32.x host by [https://www.elastic.co/guide/en/elasticsearch/reference/5.6/installing-xpack-es.html installing X-Pack] and preparing the indexes using the Migration Assistant. [https://github.com/elastic/elasticsearch/issues/30085#issuecomment-685286211 It does not work!]. And you'll avoid the hassle of registering for a (free) limited license. Plus the hassle of installing and upgrading Kibana just to get the Migration Assistant.
