I am trying to reindex url-2016.03.01 (index) into a new index (adg-2016.03.01) and I am getting the following error. The reason is the old index was created before we made some changes to the template. Please help > curl -XPUT '[http://localhost:9200/\_reindex?index=adg-2016.03.01&type=\*&searchIndex=url-2016.03.01](http://localhost:9200/_reindex?index=adg-2016.03.01&type=*&searchIndex=url-2016.03.01)' > {"error":"InvalidIndexNameException[[\_reindex] Invalid index name [_reindex], must not start with '_']","status":400} ---

There is a \_reindex feature going into Elasticsearch 2.3 which has yet to be released but its usage doesn't look quite like that. Are you using some other plugin? ---

is there another way to do it without using logstash. I only need to reindex the data on one index? ---

There are some scripts available on internet and on this forum. I'm pretty sure you can find examples searching "reindex" here. I know @warkolm posted a Gist several times. ---

BTW your error message indicates to me that the plugin is not loaded, means: you did not restart the nodes. ---

Thank you David, I used logstash as you suggested and it works fine. ---
