PAS-C01 Migration Practice Question
A company is migrating a highly critical SAP HANA database to AWS. They need to ensure data consistency and minimal downtime. Which approach should they use?
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 and AWS Launch Wizard
Using SAP HANA system replication (HSR) with AWS Launch Wizard ensures minimal downtime by providing real-time data replication to an AWS-hosted HANA instance, with Launch Wizard automating the setup and configuration. Option A (AMI) is incorrect because an AMI snapshots the entire server state but does not guarantee HANA data consistency and requires downtime. Option B (AWS DMS with ongoing replication) is not the best fit because DMS may not fully support HANA-specific replication features and can introduce complexity. Option C (export to S3 and import) is incorrect because it incurs significant downtime for export/import and does not provide continuous replication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an AMI of the on-premises HANA server and launch it on AWS
Why it's wrong here
AMI cannot capture on-premises servers; it's for AWS instances.
- ✗
Use AWS DMS with ongoing replication
Why it's wrong here
DMS may not support SAP HANA natively as a source for ongoing replication.
- ✗
Export HANA data to S3 and import into a new HANA instance
Why it's wrong here
This is manual and not suitable for minimal downtime.
- ✓
Use SAP HANA system replication and AWS Launch Wizard
Why this is correct
System replication provides low RPO/RTO; Launch Wizard simplifies deployment.
Quick reference
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 |

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 is migrating a critical SAP HANA database to AWS. They have a limited migration window and need to ensure data consistency. Which migration approach should they use?
medium- A.Use AWS Backup to restore the latest backup of the HANA database to an EC2 instance.
- ✓ B.Use SAP HANA System Replication to replicate data to a target HANA system on AWS.
- C.Perform a heterogeneous migration using AWS SCT and AWS DMS.
- D.Use AWS DMS with ongoing replication from the source HANA database to an Amazon RDS for HANA instance.
Why B: SAP HANA System Replication with HLI or EC2 allows near-zero downtime and data consistency. Heterogeneous migration with DMS and SCT is for different database engines. Backup and restore may have longer downtime. SAP Landscape Transformation is for system consolidation, not direct HANA migration.
