Hey,  
We have over 1000 rollover indices on produciton servers. How to we migrate this environment to the data stream setup? How does the migrate path looks like?

Thanks a lot,  
Nils

Thanks for using elasticsearch!

The next minor realease will offer an API to migrate an alias to a data stream. More details about the API [here](https://www.elastic.co/guide/en/elasticsearch///reference/master/indices-migrate-to-data-stream.html)
