 ## Convert an index alias to a data stream [convert-index-alias-to-data-stream]

 Prior to {{es}} 7.9, you’d typically use an [index alias with a write index](../../lifecycle/index-lifecycle-management/tutorial-time-series-without-data-streams.md) to manage time series data. Data streams replace this functionality, require less maintenance, and automatically integrate with [data tiers](../../lifecycle/data-tiers.md).
 
-To convert an index alias with a write index to a data stream with the same name, use the [migrate to data stream API](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-migrate-to-data-stream). During conversion, the alias’s indices become hidden backing indices for the stream. The alias’s write index becomes the stream’s write index. The stream still requires a matching index template with data stream enabled.
