- A
Take a full backup of Oracle, restore to SAP HANA, and then apply incremental logs.
Why wrong: This approach is possible but requires more downtime than HSR.
- B
Use SAP HANA System Replication to initially load data from the source SAP HANA (or migrate using SAP DMO with SUM) and then switch over.
SAP HANA System Replication allows near-zero downtime migration by replicating data while source is online.
- C
Use the AWS Database Migration Service (DMS) to perform an online migration from Oracle to SAP HANA.
Why wrong: DMS does not support SAP HANA as a target for heterogeneous migrations.
- D
Perform an export/import using SAP tools while the source database is online.
Why wrong: Export/import requires downtime or has high latency.

PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating its SAP ERP system running on Oracle to SAP HANA on AWS. The system has a database size of 2 TB. During migration planning, the team needs to minimize downtime. Which strategy should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 to initially load data from the source SAP HANA (or migrate using SAP DMO with SUM) and then switch over.
Option B is correct because SAP DMO (Database Migration Option) with SUM (Software Update Manager) is the recommended approach for migrating SAP systems to SAP HANA with minimal downtime. It performs a heterogeneous migration directly from Oracle to SAP HANA, using a combination of initial data load and subsequent delta replication to reduce the final cutover window. This method is specifically designed for SAP landscapes and supports near-zero downtime migration scenarios.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Take a full backup of Oracle, restore to SAP HANA, and then apply incremental logs.
Why it's wrong here
This approach is possible but requires more downtime than HSR.
- ✓
Use SAP HANA System Replication to initially load data from the source SAP HANA (or migrate using SAP DMO with SUM) and then switch over.
Why this is correct
SAP HANA System Replication allows near-zero downtime migration by replicating data while source is online.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept

- ✗
Use the AWS Database Migration Service (DMS) to perform an online migration from Oracle to SAP HANA.
Why it's wrong here
DMS does not support SAP HANA as a target for heterogeneous migrations.
- ✗
Perform an export/import using SAP tools while the source database is online.
Why it's wrong here
Export/import requires downtime or has high latency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume AWS DMS can handle any database migration, but it lacks support for SAP HANA as a target and cannot manage SAP-specific metadata and dependencies required for a successful migration.
Detailed technical explanation
How to think about this question
SAP DMO with SUM leverages the SAP HANA migration cockpit to perform an initial load of table structures and data, then uses trigger-based replication to capture ongoing changes from the source Oracle database. During the final switchover, only the delta changes are applied, significantly reducing downtime to minutes rather than hours. This approach also handles SAP-specific objects like ABAP dictionaries and custom code modifications automatically, which generic tools cannot manage.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
