Hi I never had a deal with scripting and API. I have one ELK on-demand instance and for example there are 10 clients and all indices have format aka "logstash-2019.01.01-000001". How to build script that will reindex data and I can choose what client data should be reindexed? ---

I am not sure I fully got the question, so feel free to expand (for example with a sample dataset), but you could use the [reindex API](https://www.elastic.co/guide/en/elasticsearch/reference/7.1/docs-reindex.html) in combination with a query that filters for your clients data and then specify a different index for each of your clients. Hope this helps! ---
