Indices created before 0.90
editElasticsearch 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.
