Installation and Upgrade

You can use the Reindex API to migrate indices from the old 2.x Elasticsearch cluster to a new 6.x Elasticsearch cluster.

For more information, see https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html#reindex-from-remote.

Procedure

  1. Add the following configuration parameter to the elasticsearch.yml file of your new 6.x Elasticsearch cluster to enable it to access your old Elasticsearch cluster: 
    reindex.remote.whitelist: oldhost:*
  2. Replace oldhost with the Elasticsearch host.
    Do not specify the Elasticsearch port but set value to * or you may get the following error message: "[oldhost:9200] not whitelisted in reindex.remote.whitelist"
  3. Restart the Elasticsearch cluster.
