AWS Database Migration Service

AWS Database Migration Service (DMS) enables database migration to AWS with Schema Conversion Tool (SCT) providing AI-assisted schema and code conversion. DMS pricing based on instance hours (starting ~$0.02/hour for t2.micro) plus data transfer. SCT is free. The service supports homogeneous (same engine) and heterogeneous (cross-engine) migrations with continuous replication for minimal downtime. Schema Conversion Tool uses rule-based and ML approaches to convert stored procedures, functions, and application code between database engines (Oracle to PostgreSQL, SQL Server to Aurora, etc.). Migration assessment reports identify incompatibilities before migration. Supports sources including Oracle, SQL Server, MySQL, PostgreSQL, MongoDB, SAP, and mainframe databases. DMS Serverless automatically provisions and scales replication capacity. For AI-enhanced migration: SCT reduces manual conversion work while assessment reports prioritize engineering effort. Page should cover: DMS vs SCT roles, supported migration paths matrix, assessment report interpretation, CDC for continuous replication, Serverless vs provisioned, comparison with Azure Migrate, and migration planning best practices.
