# Clean up detection alert migrations

deprecated

- Server: `https://{kibana_url}`

## Paths

- `DELETE` `/api/detection_engine/signals/migration`
- `DELETE` `/s/{space_id}/api/detection_engine/signals/migration`

- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/kibana/v8/authentication#apikeyauth)
- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/kibana/v8/authentication#basicauth)

## Description

Refer to [Spaces](https://www.elastic.co/docs/deploy-manage/manage-spaces) for more information.

Migrations favor data integrity over shard size. Consequently, unused or orphaned indices are artifacts of
the migration process. A successful migration will result in both the old and new indices being present.
As such, the old, orphaned index can (and likely should) be deleted.

While you can delete these indices manually,
the endpoint accomplishes this task by applying a deletion policy to the relevant index, causing it to be deleted
after 30 days. It also deletes other artifacts specific to the migration implementation.
