DBS-C01 Deployment and Migration Practice Question
A company wants to migrate its Oracle data warehouse to Amazon Redshift. The source database is 10 TB and has many complex stored procedures. Which AWS service should be used primarily for converting the stored procedures to Amazon Redshift compatible code?
⚠ Common exam trap
Watch out — candidates often confuse AWS DMS (which moves data) with AWS SCT (which converts schema and code), leading them to choose DMS for stored procedure conversion when DMS cannot translate procedural logic at all.
Answer choices
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 the correct choice because it is specifically designed to convert database schemas and complex code objects, such as stored procedures, functions, and packages, from one database engine to another. For an Oracle-to-Amazon Redshift migration, AWS SCT can automatically translate Oracle PL/SQL stored procedures into Amazon Redshift compatible SQL (e.g., using PL/pgSQL or SQL functions), handling syntax differences and unsupported features. This makes it the primary tool for converting the 10 TB data warehouse's stored procedures, whereas other services focus on data movement or ETL, not schema and code conversion.
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 Glue
Why it's wrong here
Glue is an ETL service, not specialized for schema conversion.
- ✗
AWS Database Migration Service (AWS DMS)
Why it's wrong here
DMS migrates data but does not convert stored procedures.
- ✗
Amazon Redshift COPY command
Why it's wrong here
COPY loads data from S3 into Redshift, not for schema conversion.
- ✓
AWS Schema Conversion Tool (AWS SCT)
Why this is correct
SCT converts schema and code objects like stored procedures to target engine syntax.
