PAS-C01 Migration Practice Question
A company is migrating a legacy SAP ECC 6.0 system running on IBM AIX with DB2 to SAP S/4HANA on AWS. The current DB2 database is 4 TB and has extensive use of stored procedures and triggers. The migration window is 48 hours. Which migration strategy is MOST appropriate?
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 and convert to SAP HANA.
For migrating SAP ECC to S/4HANA with a database migration, SAP's Software Update Manager (SUM) with Database Migration Option (DMO) is the recommended tool. DMO performs both the software update (to S/4HANA) and the database migration (from DB2 to HANA) in a single process. Option B (AWS SMS) only replicates the server, not the database conversion. Option C (SLT) is for ongoing replication, not one-time migration. Option D (AWS DMS) does not support SAP-specific database objects like stored procedures and triggers.
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 SAP Software Update Manager (SUM) with Database Migration Option (DMO) to migrate and convert to SAP HANA.
Why this is correct
SUM with DMO is the SAP-recommended tool for migrating from any DB to SAP HANA while converting the system.
- ✗
Use AWS Server Migration Service (AWS SMS) to replicate the entire AIX server to AWS, then install SAP HANA.
Why it's wrong here
AWS SMS replicates the entire OS, but DB2 to HANA requires a database-level migration, not OS-level.
- ✗
Use SAP Landscape Transformation (SLT) to replicate data to SAP HANA in real time and then cut over.
Why it's wrong here
SLT is for ongoing data replication, not a one-time migration with system conversion.
- ✗
Use AWS Database Migration Service (AWS DMS) with ongoing replication to migrate the database to SAP HANA.
Why it's wrong here
AWS DMS does not support SAP HANA as a target for heterogeneous migrations with stored procedures.
