== Breaking changes in 2.0
|
|
|
|
This section discusses the changes that you need to be aware of when migrating
|
|

=== Indices created before 0.90
|
|
|
|
Elasticsearch 2.0 can read indices created in version 0.90 and above. If any
|
|
of your indices were created before 0.90 you will need to upgrade to the
|
|
latest 1.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.

|
=== Elasticsearch migration plugin
|
|
|
|
We have provided the https://github.com/elastic/elasticsearch-migration[Elasticsearch migration plugin]
|
|
to help you detect any issues that you may have when upgrading to
|
|
Elasticsearch 2.0. Please install and run the plugin *before* upgrading.
