PAS-C01 Migration Practice Question
A company is migrating a large SAP S/4HANA system (8 TB total data, high I/O) from on-premises to AWS. The SAP system runs on HANA database and uses a three-tier architecture with application servers and database servers. The migration plan must minimize downtime and ensure data consistency. The company has a 10 Gbps direct connection to AWS. They have considered using AWS DMS, but the database is SAP HANA, which is not supported as a source by DMS. The migration team needs to transfer the HANA database and also the application files. They also need to replicate ongoing changes to minimize downtime. Which combination of AWS services should the migration team use? (Choose the best answer.)
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 AWS Application Migration Service (MGN) for the application servers. Use HANA Backint agent to back up the database to S3 and perform incremental backups for ongoing replication.
AWS DMS does not support SAP HANA as a source, eliminating options C and D. Option B (DataSync) can copy files but lacks ongoing replication to minimize downtime. Option A uses AWS MGN to replicate application servers continuously, and HANA Backint agent to back up the HANA database to S3 with incremental backups, enabling point-in-time recovery and minimal downtime. This combination addresses both the database and application migration requirements effectively.
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 AWS Application Migration Service (MGN) for the application servers. Use HANA Backint agent to back up the database to S3 and perform incremental backups for ongoing replication.
Why this is correct
MGN can replicate the application servers with minimal downtime. HANA Backint to S3 allows full and incremental backups, enabling point-in-time recovery and minimal downtime.
- ✗
Use AWS DataSync to copy the entire HANA database files (data and log volumes) and application files to AWS. Then restore from the copied files.
Why it's wrong here
DataSync is not designed for database replication and cannot capture ongoing changes for minimal downtime.
- ✗
Use AWS Database Migration Service (DMS) with SAP HANA as a source by installing a custom connector. Use AWS DataSync for application files.
Why it's wrong here
DMS does not support SAP HANA as a source, even with custom connectors.
- ✗
Use AWS DMS for the HANA database using a homogeneous migration. Use AWS MGN for the application servers.
Why it's wrong here
DMS does not support homogeneous migration for HANA as a source.

| 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 |
