Overview of the Conversion Process
Preparation Phase
SAP provides a process for the conversion to SAP S/4HANA foundation. Before starting the realization phase of the conversion process, you have to do the following preparatory activities:
- Planning
You need to gain an idea of the project steps and necessary preparations. Use the Roadmap Viewer to familiarize yourself with the project steps required for the transition to SAP S/4HANA foundation. For more information, see https://roadmapviewer-supportportal.dispatcher.hana.ondemand.com/.
- System requirements
You need to be aware of system requirements, start releases, conversion paths, and data volume. See the following sections for more information:
- Maintenance Planner
You need to run the Maintenance Planner tool as a first step in the conversion process. It checks your components, add-ons, and business functions to ensure compatibility with SAP S/4HANA foundation and also creates the stack file used for the actual conversion process (done by the Software Update Manager tool). For more information, see Maintenance Planner.
- Cross-application preparation activities
In addition to the general preparation steps described above, you also need to do some cross-application preparations. For more information, see Cross-Application Preparations.
Realize Phase
After you have executed the steps in the preparation phase, you can continue with the activities of the realize phase using the Software Update Manager (SUM). The Software Update Manager does the database migration (if required), the actual software update, and the data conversion. For more information, see Realizing the Conversion.
