PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is planning to migrate its SAP ECC system to SAP S/4HANA on AWS. The current system uses an IBM Db2 database on-premises. The target system will use SAP HANA as the database. The company wants to perform the migration with minimal downtime. Which tool or method should be used?
⚠ Common exam trap
Many candidates confuse real-time replication tools like SLT or AWS DMS with the specialized SAP DMO process, not realizing that only DMO combines the database migration, system upgrade, and minimal downtime in a single, SAP-supported workflow.
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 the Database Migration Option (DMO).
SAP Software Update Manager (SUM) with the Database Migration Option (DMO) is the only tool that combines both the system upgrade from SAP ECC to SAP S/4HANA and the database migration from IBM Db2 to SAP HANA in a single, integrated process. DMO uses a trigger-based replication approach to minimize downtime by migrating data in the background while the source system remains operational, then performing a short final cutover. This is the officially recommended SAP methodology for heterogeneous migrations with minimal downtime.
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 IBM Db2 native tools to export the database and import into HANA.
Why it's wrong here
Not designed for SAP HANA migration.
- ✗
Use AWS Database Migration Service (DMS) to replicate data from Db2 to HANA.
Why it's wrong here
DMS does not fully support Db2 to HANA for SAP systems.
- ✓
Use SAP Software Update Manager (SUM) with the Database Migration Option (DMO).
Why this is correct
SUM with DMO supports migration from Db2 to HANA with minimal downtime.
- ✗
Use SAP Landscape Transformation (SLT) to replicate data in real-time.
Why it's wrong here
SLT is for ongoing replication, not one-time migration.
