PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating its SAP Business Warehouse (BW) system to AWS. The source system runs on an on-premises IBM AIX server with an Oracle database. The target AWS environment will use SAP HANA as the database. The migration tool is SAP Software Provisioning Manager (SWPM). The company has a requirement to minimize downtime during the migration. The SAP BW system has 5 TB of data. The network bandwidth between on-premises and AWS is 1 Gbps. The migration team plans to use AWS Direct Connect for the data transfer. They estimate that the initial data load will take approximately 12 hours. However, the cutover window is limited to 8 hours. What should the migration team do to meet the cutover window?
⚠ Common exam trap
Watch out — candidates often assume increasing network bandwidth (Option D) is the only solution to meet the cutover window, overlooking the fact that the initial data load time is dominated by database export and import processing, not just network transfer speed.

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 Landscape Transformation (SLT) to replicate data in real-time after the initial load, and then perform a final delta sync during the cutover window.
SAP Landscape Transformation (SLT) can replicate data in near real-time from the source Oracle database to the target SAP HANA using trigger-based replication. After the initial 12-hour data load is completed before the cutover window, SLT captures ongoing changes and applies them during the final delta sync within the 8-hour cutover window, minimizing downtime. This approach decouples the lengthy initial load from the limited cutover period, meeting the requirement.
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 DataSync to accelerate the data transfer and then import into HANA.
Why it's wrong here
DataSync is not designed for SAP database migration.
- ✓
Use SAP Landscape Transformation (SLT) to replicate data in real-time after the initial load, and then perform a final delta sync during the cutover window.
Why this is correct
SLT enables delta replication, reducing cutover time.
- ✗
Perform a HANA system replication from the source to the target after the initial load.
Why it's wrong here
HANA system replication is not supported from Oracle to HANA.
- ✗
Request a higher bandwidth Direct Connect connection to reduce the initial load time to under 8 hours.
Why it's wrong here
Bandwidth upgrade may not be possible quickly and may not solve the entire issue.
