DBS-C01 Deployment and Migration Practice Question
A company wants to migrate its on-premises Oracle database to Amazon Aurora PostgreSQL. The company needs to automatically convert the Oracle schema to PostgreSQL-compatible format. Which AWS service should the company use?
⚠ Common exam trap
A common mix-up: candidates confuse AWS DMS's data migration capability with schema conversion, assuming DMS can automatically transform the schema, when in fact DMS only moves data and requires SCT for schema translation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Schema Conversion Tool (AWS SCT)
AWS Schema Conversion Tool (AWS SCT) is designed specifically to convert database schemas from one engine to another, including Oracle to Amazon Aurora PostgreSQL. It automatically translates Oracle DDL (tables, indexes, stored procedures, functions, etc.) into PostgreSQL-compatible format, handling data type mappings, PL/SQL to PL/pgSQL conversion, and other schema-level transformations. AWS DMS handles data migration, not schema conversion, making SCT the correct choice for this requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Database Migration Service (AWS DMS) with the Oracle native dump and load option
Why it's wrong here
Native dump/load does not convert schema; AWS SCT is needed for schema conversion.
- ✗
AWS Server Migration Service (AWS SMS)
Why it's wrong here
AWS SMS is for migrating on-premises servers to AWS, not for database schema conversion.
- ✗
AWS Database Migration Service (AWS DMS)
Why it's wrong here
AWS DMS migrates data but does not automatically convert schema; schema conversion must be done separately with AWS SCT.
- ✓
AWS Schema Conversion Tool (AWS SCT)
Why this is correct
AWS SCT automates schema conversion from Oracle to Amazon Aurora PostgreSQL.
