Hi, I'm trying to think of a better approach than this (bearing in mind our application and logs and ES is on-prem): a) Customer sends an `elasticdump` of their data and their indexes will be in the format of `fluend-YYYYMMDD` b) We use `elasticdump` to import this into our local ES to analyse logs. c) Call the REINDEX api to rename their indexes CustomerFoo-YYYYMMDD (As a side note you can call the REINDEX API with a source of `fluentd*` and it will merge all indexes into the destination - [https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docs-reindex.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docs-reindex.html)) Can anyone think of a better way where they can export their data and we can reimport with a specific index name? ---
