Migration to HANA made easy with DMO
DMO – Intro
DMO is an option of SUM (Software Update Manager) for a combined update and migration: update an existing SAP system to a higher Software Release and migrate to SAP HANA database. The procedure is only available for systems based on AS ABAP, hence the executable SAPup is used in background. DMO migrates from an existing relational database type (“anyDB”) to SAP HANA. Software Update Manager (SUM) is the tool for system maintenance: Release upgrades, EHP implementation, applying SP stacks.
Prerequisites
- The SAP system has to be a single ABAP stack, so a dual-stack split may be required before.
- For non-unicode systems, the procedure will include a Unicode-conversion which is planned to be implemented in SUM1.0 SP10.
- Source system release has to be based on SAP NetWeaver 7.0 SP17 or higher.
- Target system release has to be based on SAP NetWeaver 7.31 (or higher).
- Regarding the source database, all versions listed in the PAM of the source release are supported.
- Regarding the operating system, all version listed in the PAM of the target release are supported.
