Indices created before 7.0

Elasticsearch 7.0 can read indices created in version 6.0 or above. An Elasticsearch 7.0 node will not start in the presence of indices created in a version of Elasticsearch before 6.0.

Important

Reindex indices from Elasticsearch 5.x or before Indices created in Elasticsearch 5.x or before will need to be reindexed with Elasticsearch 6.x in order to be readable by Elasticsearch 7.x.
