SAP HANA Data Migration Option

2 Views

DMO for SAP NetWeaver BW and for SAP Business Suite systems
DMO is available with Software Update Manager 1.0 SP09 and higher, and can be used for systems based on AS ABAP. It can be used for SAP BW systems from 7.0 SP17 (and higher) to migrate to 7.31 (and higher). And it can be used for systems like SAP R/3 4.6C or systems part of the SAP Business Suite 7.0 (and higher) to migrate to a level corresponding to SAP BASIS 7.40 (for example "SAP enhancement package 7 for SAP ERP 6.0").

DMO processing overview
The processing sequence is based on the shadow system functionality of SUM: the SUM creates the shadow repository on the traditional database until downtime phase, while in parallel the SAP HANA database is setup (client, schema, ...). Then the shadow repository is copied to SAP HANA, the database connection of the SAP system is switched to SAP HANA database, and then the downtime starts. After migration of the application data (including data conversion), the upgrade is finalized and the SAP system runs on SAP HANA. The traditional database continues to run and the application data in it are not modified, so it remains a fallback throughout the complete process.

DMO is using SAPUI5
DMO is based on the "standard" SUM, for which a new user interface (UI) was introduced. The UI is based on SAPUI5, so it's running in a browser, and offers some comfortable features like checking the log files without having to log on to the OS of the application server.
