The SAP Software Update Manager (SUM) with its Database Migration Option (DMO) feature is the designated SAP tool for this scenario. It combines a system update, conversion, or upgrade with a database migration (e.g., from AnyDB to SAP HANA) into a single, highly optimized procedure. The "DMO with System Move" capability specifically supports migrating to a different infrastructure, such as from on-premises to Azure. This one-step approach significantly minimizes downtime and administrative effort compared to a traditional two-step export/import migration using other tools.

A. SAP Software Provisioning Manager: SWPM is used for new installations or classic two-step migrations (export/import). This method typically involves more downtime and administrative steps than the integrated SUM with DMO process.

C. Azure Migrate: Azure Migrate is an infrastructure migration service for moving VMs and servers to Azure. It does not perform the application-specific database replatforming from SAP AnyDB to SAP HANA.

D. Azure Database Migration Service: This service is for migrating non-SAP databases (like SQL Server, Oracle) to Azure PaaS database offerings. It does not support the application-aware migration required for SAP systems to HANA.

Azure Architecture Center

"SAP S/4HANA in Linux on Azure": This document outlines migration strategies. Under the "Migration to S/4HANA" section

it states

"For migrations from an existing SAP ERP system to S/4HANA

the SAP Software Update Manager (SUM) tool is the officially supported and recommended tool. It offers a path that combines the software update and the database migration to SAP HANA (if applicable) in one tool." This confirms SUM as the primary tool for combined updates and HANA migration.

Azure Virtual Machines

"SAP workload on Azure: planning and deployment checklist": In the "Migration phase" section

this guide discusses migration methodologies. It explicitly lists "Using SAP Software Update Manager (SUM) with Database Migration Option (DMO)" as a key method for migrating to Azure

highlighting its efficiency for combining tasks.

3. SAP Help Portal

"Database Migration Option (DMO) of Software Update Manager 2.0 SP17": The official SAP documentation describes the tool's purpose: "The Database Migration Option (DMO) of Software Update Manager (SUM) is the process for migration to a different database... DMO can be used to migrate to SAP HANA database... The DMO procedure combines the database migration with the software update." This directly supports its use for minimizing downtime by combining steps.
