PAS-C01 Migration Practice Question
A company is migrating a production SAP HANA database to AWS. The database size is 2 TB. The migration window is 4 hours. The network bandwidth is 10 Gbps. Which migration method should be used to achieve the shortest downtime?
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
✓
Use SAP HANA System Replication.
SAP HANA System Replication can achieve near-zero downtime, which is critical for a 2 TB database with a 4-hour migration window. With 10 Gbps bandwidth, initial sync completes well within the window, and ongoing replication minimizes downtime during cutover. Backup and restore (A) would likely exceed 4 hours due to data size. AWS DMS with CDC (B) introduces overhead and is not optimized for HANA system replication. AWS Snowball Edge (D) is unnecessary given the high bandwidth and would add latency for initial load.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a backup and restore approach.
Why it's wrong here
Backup and restore may exceed the migration window.
- ✗
Use AWS DMS with full load and CDC.
Why it's wrong here
Full load may take time; CDC requires ongoing replication.
- ✓
Use SAP HANA System Replication.
Why this is correct
System Replication provides the shortest downtime, often minutes.
- ✗
Use AWS Snowball Edge for initial load, then CDC.
Why it's wrong here
Unnecessary given 10 Gbps bandwidth.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company wants to migrate a 50 TB SAP HANA database to AWS with minimal downtime. Which migration approach should be used?
easy- ✓ A.Configure SAP HANA System Replication (HSR) between source and target.
- B.Export the database to a file and upload to Amazon S3, then restore on RDS for HANA.
- C.Use AWS SCT to convert the HANA schema to Aurora.
- D.Use AWS DMS with ongoing replication from HANA to HANA.
Why A: 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.
