Hi,

I would like to if it is possible to upgrade my existing Elasticsearch v6.3.0 to v7.7.0, without introducing an intermediate version? Below is the rolling upgrade link.

[https://www.elastic.co/guide/en/elasticsearch/reference/7.7/rolling-upgrades.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.7/rolling-upgrades.html)

Thank you.

You can reindex the data in the new cluster. Using reindex from remote for example.

Per the doc you linked to, no;

> Rolling upgrades are supported:
> 
> - Between minor versions
> - [From 5.6 to 6.8](https://www.elastic.co/guide/en/elastic-stack/6.8/upgrading-elastic-stack.html)
> - From 6.8 to 7.7.1
> - From any version since 7.7.0 to 7.7.1
> 
> Upgrading directly to 7.7.1 from 6.7 or earlier requires a [full cluster restart](https://www.elastic.co/guide/en/elasticsearch/reference/current/restart-upgrade.html).
