-In this tutorial we’ll look at migrating an existing data stream from [Index Lifecycle Management ({{ilm-init}})](../index-lifecycle-management.md) to [data stream lifecycle](../data-stream.md). The existing {{ilm-init}} managed backing indices will continue to be managed by {{ilm-init}} until they age out and get deleted by {{ilm-init}}; however, the new backing indices will be managed by data stream lifecycle. This way, a data stream is gradually migrated away from being managed by {{ilm-init}} to being managed by data stream lifecycle. As we’ll see, {{ilm-init}} and data stream lifecycle can co-manage a data stream; however, an index can only be managed by one system at a time.

+Learn to apply and manage lifecycle policies for integrations data stored in Elasticsearch. This documentation covers default policies for Elastic integrations, how to override them, and how to align retention rules with your requirements.
 
 An Elastic integration is a pre-packaged collection of assets that provides an effective, simplified way to monitor a product, system, or service, with minimal required setup. Most integrations rely on {{agent}} as an ingest mechanism, and the policies used to govern installed integrations are managed in {{fleet}}.
