Is it necessary to be running Elasticsearch 7.17.28 before upgrade to 8? An instance of Kibana upgrade assistant doesn't say anything about having to upgrade from 7.17.x that it's looking at. I can't find any documentation which explains version requirements before upgrading, but I'm sure I've seen such in the past about previous major version upgrades. ---

See [these docs](https://www.elastic.co/guide/en/elasticsearch/reference/8.18/setup-upgrade.html): > To upgrade to 8.18.2 from 7.16 or an earlier version, **you must first upgrade to 7.17**... Technically you don't need to go all the way to 7.17.28, any 7.17.x version will do, but 7.17.28 is safest. ---
