[[breaking-changes-6.0]]
== Breaking changes in 6.0
This section discusses the changes that you need to be aware of when migrating
your application to Elasticsearch 6.0.
[float]
=== Indices created before 6.0
Elasticsearch 6.0 can read indices created in version 5.0 or above. An
Elasticsearch 6.0 node will not start in the presence of indices created in a
version of Elasticsearch before 5.0.
[IMPORTANT]
.Reindex indices from Elasticseach 2.x or before
=========================================
Indices created in Elasticsearch 2.x or before will need to be reindexed with
Elasticsearch 5.x in order to be readable by Elasticsearch 6.x. The easiest
way to reindex old indices is to use the `reindex` API.
=========================================

Remove allow unquoted JSON Previous versions of Elasticsearch permitted unquoted JSON field names even though this is against the JSON spec. This leniency was disabled by default in the 5.x series of Elasticsearch but a backwards compatibility layer was added via a system property with the intention of removing this layer in 6.0.0. This commit removes this backwards compatibility layer. Relates #20388

No longer allow cluster name in data path In 5.x we allowed this with a deprecation warning. This removes the code added for that deprecation, requiring the cluster name to not be in the data path. Resolves #20391

Remove mapper attachments plugin We now have in 5.0.0 `ingest-attachment` plugin. We can remove `mapper-attachments` plugin for 6.0. Closes #18837.

Remove FORCE version_type This was an error-prone version type that allowed overriding previous version semantics. It could cause primaries and replicas to be out of sync however, so it has been removed. Resolves #19769
