- A
Use AWS Lambda to automatically convert the stored procedures.
Why wrong: Lambda is not a schema conversion tool; manual rewriting is required.
- B
Use AWS DMS to replicate the Oracle stored procedures as-is to Aurora.
Why wrong: DMS migrates data, not schema objects like stored procedures.
- C
Switch to Amazon RDS for Oracle to avoid conversion issues.
Why wrong: The goal is to migrate to Aurora PostgreSQL, not stay on Oracle.
- D
Manually rewrite the unconverted stored procedures to PostgreSQL-compatible code based on SCT's assessment report.
SCT provides a report of items that need manual attention; rewriting is necessary.

SCT Stored Procedures Failed Conversion: Manual Rewrite Based on Assessment
This DBS-C01 practice question tests your understanding of deployment and migration. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating an on-premises Oracle database to Amazon Aurora PostgreSQL. They used AWS SCT to convert the schema, but some stored procedures failed to convert automatically. What is the best course of action?
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
✓
Manually rewrite the unconverted stored procedures to PostgreSQL-compatible code based on SCT's assessment report.
AWS SCT provides an assessment report that identifies unconverted stored procedures and suggests manual rewrites. Since Oracle and PostgreSQL have fundamentally different procedural languages (PL/SQL vs. PL/pgSQL), automated conversion cannot handle all syntax and semantic differences. Manually rewriting the unconverted procedures based on SCT's report ensures compatibility and correctness, as SCT highlights the specific lines and constructs that need attention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Use AWS Lambda to automatically convert the stored procedures.
Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume AWS DMS can handle stored procedure migration (Option B) because DMS handles schema conversion for tables, but DMS explicitly does not migrate stored procedures, triggers, or other programmatic objects.
Detailed technical explanation
How to think about this question
Oracle stored procedures use PL/SQL with packages, autonomous transactions, and REF CURSORs that have no direct equivalent in PostgreSQL. SCT's assessment report provides a 'Action Items' table with line-by-line mapping of unconverted code, including severity levels and suggested manual fixes. In practice, common issues include Oracle's %TYPE and %ROWTYPE attributes, which must be replaced with explicit data types, and Oracle's CONNECT BY PRIOR hierarchical queries, which require recursive CTEs in PostgreSQL.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
