PAS-C01 Migration Practice Question
A company is migrating its SAP Business Suite system from on-premises to AWS. The system uses a Sybase ASE database. The migration team has limited Sybase expertise. They want to minimize the operational overhead after migration. Which database migration approach should they choose?
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 Software Update Manager (SUM) with Database Migration Option (DMO) to migrate the system to SAP HANA on EC2.
Migrating from Sybase ASE to SAP HANA is a strategic move that reduces operational overhead because HANA is a modern in-memory database with better performance and simpler management. SAP Software Update Manager (SUM) with Database Migration Option (DMO) is the official SAP tool to perform this migration while also upgrading the SAP system. This approach minimizes manual effort and leverages SAP expertise. Option A is incorrect because AWS Application Migration Service (MGN) would replicate the entire Sybase server, keeping Sybase and not reducing overhead. Option C is incorrect because AWS DataSync is designed for file-based transfers, not database replication. Option D is incorrect because AWS DMS does not support Sybase as a target database, and Amazon RDS does not support Sybase; Sybase on AWS would require self-managed EC2, increasing overhead.
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 MGN to replicate the entire Sybase server to EC2, then perform a system upgrade to SAP HANA.
Why it's wrong here
MGN replicates the server as-is; upgrading to HANA is a separate, complex process that is not part of MGN.
- ✓
Use SAP Software Update Manager (SUM) with Database Migration Option (DMO) to migrate the system to SAP HANA on EC2.
Why this is correct
DMO allows migrating from Sybase to HANA as part of a system update, reducing overhead and leveraging SAP expertise.
- ✗
Use AWS DataSync to copy the Sybase data files to EBS and attach to an EC2 instance running Sybase.
Why it's wrong here
This does not reduce operational overhead and does not address the lack of Sybase expertise.
- ✗
Use AWS DMS to migrate the Sybase database to Amazon RDS for Sybase.
Why it's wrong here
Amazon RDS does not support Sybase ASE as a database engine.
