Update given indices by index template

Elastic Stack Elasticsearch

Hi,

i've created a index_template.

There exist a lot of indices with more than 40 million documents. Is it possible update existing index by the template instaed to reindex all?

The _update_by_query doesn't do the job...

You can reindex into a new index that matches the template, yes.

Sorry there was an error in my question:

Is it possible update existing indices by the template instead to reindex all

No you cannot do that, it needs a reindex.
