PAS-C01 Migration Practice Question
A company is migrating an SAP ERP system running on an on-premises IBM AIX server to AWS. The server hosts both the SAP application and the DB2 database. The company has a tight deadline and wants to minimize the migration effort. The current system uses a storage area network (SAN) with 2 TB of data. The company wants to use AWS native services and avoid re-architecting. What is the BEST migration strategy?

Correct answer & explanation
✓
Use AWS Application Migration Service (MGN) to replicate the entire server to AWS.
AWS MGN supports migration of IBM AIX servers with block-level replication. Option B (manual install) is wrong because manual installation is more effort and not leveraging AWS services. Option C is wrong because AWS Snowball would require downtime and is not real-time. Option D is wrong because AWS DMS does not support DB2 on AIX as a source.
