Hello, It is possible through the API to remove 3 shards to all existing index? Don't care if data will be lost. Thank you.

If you are on Elasticsearch 5.x you can also use the shrink index API.

Removing shards

Ok, that's what I supposed.
I will purge all index and recreate them with less shards.

Thank you :).
