Migration of SAP Workloads to AWS

Question

A company is planning to migrate its on-premises SAP application to AWS. The application runs on VMware vSphere. The SAP ERP Central Component (SAP ECC) server runs on an IBM Db2 database that is 2 TB in size. The company wants to migrate the database to SAP HANA. Which migration strategy will meet these requirements?

Options

AUse AWS Application Migration Service (CloudEndure Migration).
BUse SAP Software Update Manager (SUM) Database Migration Option (DMO) with System Move.
CUse AWS Server Migration Service (AWS SMS).
DUse AWS Database Migration Service (AWS DMS).

Explanation

This migration has two simultaneous goals: (1) move the system from on-premises VMware to AWS EC2, and (2) change the underlying database platform from IBM Db2 to SAP HANA. Only an SAP-native tool can accomplish both at once.

Why B (SAP SUM DMO with System Move) is correct: SAP Software Update Manager (SUM) with the Database Migration Option (DMO) is the SAP-certified process specifically designed to migrate SAP systems from one database engine to another (heterogeneous migration, e.g., Db2 → HANA) while simultaneously relocating the system to new target hardware or cloud infrastructure ('System Move'). It understands SAP's internal data structures, handles table transformations required for HANA column-store format, and is the supported path for this exact scenario.

Why the others are wrong:

A (AWS Application Migration Service / CloudEndure): Performs lift-and-shift replication of VMs. It copies the existing Db2 instance as-is to AWS - it does not convert the database engine to SAP HANA.
C (AWS Server Migration Service): Also a VM lift-and-shift tool. Same limitation - it migrates the OS and Db2 intact, without any database platform conversion.
D (AWS Database Migration Service): AWS DMS is a general-purpose database replication service for standard databases (e.g., Oracle to Aurora). It has no awareness of SAP application-layer data semantics, SAP HANA-specific requirements, or the transformation logic needed for a Db2-to-HANA migration.
