이 페이지에서는 Database Migration Service에서 이기종 마이그레이션을 사용하여 사용할 수 있는 마이그레이션 작업(기존 대상 인스턴스의 경우, 마이그레이션 작업 구성 중에 Database Migration Service에서 대신 만드는 경우)에 대해 설명합니다.
Database Migration Service에서 만든 대상 데이터베이스
대부분의 마이그레이션 시나리오에서 Database Migration Service는 마이그레이션 작업 생성 흐름의 일부로 새 대상 데이터베이스 인스턴스를 만듭니다. Database Migration Service에서 대상 데이터베이스를 자동으로 만들도록 하려면 새 대상 인스턴스로의 마이그레이션 작업 만들기의 안내를 따르세요.
Database Migration Service 외부에서 생성된 대상 데이터베이스
마이그레이션 작업을 구성하기 전에 Database Migration Service 외부에서 대상 데이터베이스 인스턴스를 만들 수 있습니다.
이 접근 방식은 Terraform 또는 기타 코드형 인프라 도구를 사용하여 인프라를 관리할 계획인 경우에 특히 유용합니다.
Database Migration Service 외부에서 만든 대상 인스턴스로 마이그레이션하려면 고려해야 할 몇 가지 제한사항이 있습니다. 자세한 내용은 알려진 제한사항을 참고하세요.

For more information, see\n[Known Limitations](/database-migration/docs/postgres/known-limitations#existing-instance-limitations).\n\nIf you want to migrate to a destination database created outside of\nDatabase Migration Service, follow the guidance in\n[Create a migration job to an existing destination instance](/database-migration/docs/postgres/create-migration-job-existing-instance)."]]
