Elastic Stack Elasticsearch

Hi,

I have nearly 800 indices in PROD and now i have to change some mappings, is it possible to reindex all the indices at once? or do we need to reindex all one by one? and my indices are shield protected.

Thanks
Pranesh

You'll want to reindex them one by one so that you can monitor the progress, test the new indexes, and clean up the ones that you've replaced. _reindex the API is really designed to make this whole thing easier. Not automatic.
