=== 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.
|
|
|
