# Finalize detection alert migrations

**POST /api/detection_engine/signals/finalize_migration**

Finalize successful migrations of detection alerts. This replaces the original index's alias with the successfully migrated index's alias.
The endpoint is idempotent; therefore, it can safely be used to poll a given migration and, upon completion,
finalize it.
