PAS-C01 Technology Practice Question
A company runs its SAP Business Suite on AWS with an Oracle database on an EC2 instance. The database is stored on multiple EBS volumes configured as a RAID 0 array. The company wants to migrate the database to SAP HANA on a new EC2 instance. The SAP HANA instance will use EBS volumes for data and log storage. The current Oracle database size is 500 GB. The company needs to minimize downtime during the migration. Which migration strategy should they use?
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 AWS Database Migration Service (DMS) to migrate from Oracle to SAP HANA.
AWS DMS supports heterogeneous migration from Oracle to SAP HANA, enabling minimal downtime through continuous replication. SAP HANA System Replication (HSR) cannot be used because it only works between HANA systems, not from Oracle. Export/import causes extended downtime, and Application Migration Service is for server-level migration, not database-level.
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 Application Migration Service to migrate the entire EC2 instance.
Why it's wrong here
AWS Application Migration Service migrates entire servers, not databases, and cannot efficiently handle the Oracle-to-HANA migration with minimal downtime.
- ✗
Use SAP HANA System Replication to replicate data from the source Oracle database to the target HANA database.
Why it's wrong here
SAP HANA System Replication is only supported between SAP HANA systems, not from Oracle, making it invalid for this migration.
- ✗
Export the Oracle database to a flat file and import into SAP HANA.
Why it's wrong here
Exporting and importing a flat file causes extended downtime and is not optimal for minimizing disruption.
- ✓
Use AWS Database Migration Service (DMS) to migrate from Oracle to SAP HANA.
Why this is correct
AWS DMS can migrate from Oracle to SAP HANA with ongoing replication, allowing minimal downtime by keeping the source online during migration.
