# 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/v9/authentication#apikeyauth)
- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/kibana/v9/authentication#basicauth)

## Description

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

**DEPRECATED.** Cleanup API for old migration artifacts. Do not add new call sites.
**WARNING:** This schedules deletions; ensure no production reads still point at the source index.

Migrations favor data integrity over shard size. Consequently, unused or orphaned indices are artifacts of
the migration process. A successful migration can leave both the old and new indices present, so the old
index may be deleted. While you can delete these indices manually, the endpoint applies a deletion policy
to the relevant index, causing it to be deleted after 30 days, and removes other migration-specific artifacts.
