Index curation will be deprecated soon. For Elastic Stack version 6.7 and later, any deployments using index curation will be prompted to migrate to ILM.
The index lifecycle management (ILM) feature of the Elastic Stack provides an integrated and streamlined way to manage time-based data, making it easier to follow best practices for managing your indices. Compared to index curation, migrating to ILM gives you more fine-grained control over the lifecycle of each index.
For existing hot-warm deployments that are currently using index curation, there are a couple of options for migrating to index lifecycle management (ILM). You can:
- Use the migration process in the console to change an existing deployment to ILM.
- Take a snapshot and restore your data to a new Elastic Stack 6.7+ deployment that has ILM enabled.
To learn more about configuring index lifecycle management for Elasticsearch Service or about all of the features that are available with ILM, see:
To configure ILM Migration in the console:
- Log in to the Elasticsearch Service Console.
From the Deployments page, select your deployment.
Narrow your deployments by name, ID, or choose from several other filters. To customize your view, use a combination of filters, or change the format from a grid to a list.
- Set the ILM policy name for each index pattern.
Set the shard allocation attribute for the index pattern.
- You can set different node attributes per index pattern to allow for more in-depth configuration in Kibana, or
- You may choose to add one node attribute that applies to all index patterns.
- If you do not wish to migrate a certain index pattern to ILM, you can deselect the checkbox in the associated row.
- You may also wish to migrate to ILM without carrying over any of your current index patterns by deselecting all patterns. This means that those index patterns will no longer be curated, and you will have the option to set up new ILM policies in Kibana.
- Click Migrate.
After you get the notification that confirms that migration was completed successfully, you can view your ILM policies in Kibana.
