Which pair of AWS tools can be used together to migrate a commercial relational database to an Amazon-managed open-source database? (Choose two.)

AWS Database Migration Service (AWS DMS) is designed to migrate databases quickly and securely with minimal downtime. It supports migrating commercial relational databases (like Oracle or SQL Server) to open-source Amazon-managed databases (like Amazon Aurora PostgreSQL or MySQL). AWS Schema Conversion Tool (AWS SCT) works in conjunction with DMS by automatically converting the source database schema and code objects (tables, views, stored procedures, functions, etc.) to a format compatible with the target database. This pair is essential for heterogeneous database migrations. AWS SDKs are for programmatic access to AWS services, not migration itself. AWS Systems Manager is for operational insights and automation. Amazon EMR is a big data processing service.
