PAS-C01 Migration Practice Question
A company wants to migrate a 50 TB SAP HANA database to AWS with minimal downtime. Which migration approach should be used?
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
✓
Configure SAP HANA System Replication (HSR) between source and target.
SAP HANA System Replication (HSR) is the recommended method for migrating large HANA databases with minimal downtime, typically achieving near-zero downtime by replicating data continuously. Option B is incorrect because exporting the database to a file and uploading to S3 involves significant downtime for the export and restore process. Option C is incorrect because AWS SCT is used for schema conversion to different database engines, not for migrating HANA to HANA; converting to Aurora would change the database system and incur additional complexity and downtime. Option D is incorrect because AWS DMS does not support SAP HANA as a source for ongoing replication, and even if it did, HSR is more efficient for HANA-to-HANA migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure SAP HANA System Replication (HSR) between source and target.
Why this is correct
HSR provides near-zero downtime replication.
- ✗
Export the database to a file and upload to Amazon S3, then restore on RDS for HANA.
Why it's wrong here
Export/import requires significant downtime.
- ✗
Use AWS SCT to convert the HANA schema to Aurora.
Why it's wrong here
SCT is not for HANA to HANA migration.
- ✗
Use AWS DMS with ongoing replication from HANA to HANA.
Why it's wrong here
AWS DMS with ongoing replication is unsuitable for a 50 TB SAP HANA migration as it is not designed for native SAP HANA system replication. Its generic replication mechanism lacks the deep integration and performance optimisations required for large-scale, consistent HANA-to-HANA data movement with minimal downtime. However, DMS is a powerful service for heterogeneous database migrations, such as Oracle to PostgreSQL, or homogeneous migrations between different database platforms, where it effectively provides ongoing replication for reduced downtime.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
