== Breaking changes in 5.0
|
|
|
|
This section discusses the changes that you need to be aware of when migrating
|
|
your application to Elasticsearch 5.0.

|
=== Indices created before 5.0
|
|
|
|
Elasticsearch 5.0 can read indices created in version 2.0 and above. If any
|
|
of your indices were created before 2.0 you will need to upgrade to the
|
|
latest 2.x version of Elasticsearch first, in order to upgrade your indices or
|
|
to delete the old indices. Elasticsearch will not start in the presence of old
|
|
indices. To upgrade 2.x indices, first start a node which have access to all
|
|
the data folders and let it upgrade all the indices before starting up rest of
|
|
the cluster.
|
|
|
|
[IMPORTANT]
|
|
.Reindex indices from Elasticseach 1.x or before
|
|
=========================================
|
|
|
|
Indices created in Elasticsearch 1.x or before will need to be reindexed with
|
|
Elasticsearch 2.x in order to be readable by Elasticsearch 5.x. The easiest
|
|
way to do this is to upgrade to Elasticsearch 2.3 or later and to use the
|
|
`reindex` API.
|
|
