DBS-C01 Deployment and Migration Practice Question
A company wants to migrate an on-premises Oracle database to Amazon Aurora PostgreSQL. They need to convert the schema and code. Which AWS service should they use?
⚠ Common exam trap
Watch out — candidates often confuse AWS DMS with schema conversion, but DMS only moves data and requires SCT for the schema and code transformation; AWS explicitly separates these tasks in the migration process.

Correct answer & explanation
✓
AWS Schema Conversion Tool (SCT)
AWS Schema Conversion Tool (SCT) is the correct choice because it is specifically designed to convert database schemas and code objects (such as stored procedures, functions, and triggers) from one database engine to another. For an Oracle-to-Aurora PostgreSQL migration, SCT analyzes the source schema, identifies incompatible data types and syntax, and generates equivalent PostgreSQL DDL and PL/pgSQL code, handling complex conversions like Oracle sequences to PostgreSQL sequences and Oracle packages to PostgreSQL schemas.
