Hi, I have a setup of ELK7.10v. I want to reindex my data with multiple indices on monthly basis. example: My existing index should create new\_index with monthly basis. I have index1 which contains 1 year of records, and wants to sperate those 1 year records by creating monthly basis index using the log timestamp. > example: > my\_new\_index-2021-01 > my\_new\_index-2021-02 > my\_new\_index-2021-03 > my\_new\_index-2021-04 Kindly suggest, what will be the steps for doing this. Regards, Tahseen ---

You will need to use the reindex API and then add a query to only get data from each month - [https://www.elastic.co/guide/en/elasticsearch/reference/7.10/docs-reindex.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/docs-reindex.html) ---
