For the SAP ERP system, the goal is a simultaneous migration (Oracle to HANA) and a platform shift (On-premises to Azure). The SUM DMO with System Update is the standard tool for "One-Step" migrations, allowing you to upgrade the SAP application version and migrate the database to SAP HANA in a single downtime window.

For the SAP NetWeaver 7.3 Portal, the SUM DMO tool is primarily designed for ABAP stacks. Java stacks (like most portals) or older NetWeaver versions typically require a Heterogeneous System Copy using the Software Provisioning Manager (SWPM). This process exports the source database and imports it into the target HANA database on Azure, effectively handling the change in OS/DB architecture.

SAP Support Portal, SAP Note 2377305: "Case 3: Migration of an SAP system to SAP HANA using DMO." This confirms DMO is the tool for combining upgrade and migration for ABAP-based systems like ERP.

SAP Help Portal - Software Update Manager (SUM) 2.0: Section "Database Migration Option (DMO) of SUM" specifies that DMO is the preferred method for migrating to SAP HANA while performing a release upgrade.

Microsoft Azure Documentation: "SAP NetWeaver on Azure Virtual Machines (VMs) planning and implementation." This documentation outlines using SWPM for heterogeneous copies when moving non-ABAP or specific Java-based Portal components to Azure.

SAP NetWeaver Guide: "System Copy Guide: SAP Systems Based on SAP NetWeaver 7.1 to 7.5 on UNIX/Oracle," detailing the use of Software Provisioning Manager (SWPM) for heterogeneous system copies.
