Hi,
The error message already tells you what is wrong:
> [@gang\_giz](#):
>
> `was created with version [5.6.16] but the minimum compatible version is [6.0.0-beta1]. It should be re-indexed in Elasticsearch 6.x before upgrading to 7.9.0.`
As described in the upgrade documentation [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html) a direct upgrade from Elasticsearch 5.x to 6.x is not possible. You have to upgrade to a version 6.x first, then run the reindex process and migrate to 7.x afterwards.
Best regards
Wolfram

Hi,
Can we delete all index and create a fresh index with currently installed version 7.9, if so how to delete. Since my elastic is not yet started

The easiest way would be to point Elasticsearch to a new data directory.

You just have to create a new (empty) directory and update the `path.data` setting: [Node | Elasticsearch Guide [7.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.15/modules-node.html#data-path)

Hi,
I made the Path and Log Folder change and given command to start the Elasticsearch. Now it shows this error
