Downtime-Optimized Conversion

Preparation of Software Update Manager

Before starting the update with the downtime-optimized conversion to SAP S/4HANA, perform all the preparation steps mentioned in the SUM guide.

The Software Update Manager (SUM) controls the entire procedure, from checking the system requirements and importing the necessary programs through stopping production operation until production operation is resumed. The procedure is divided up into a number of different roadmap steps. The roadmap steps are in turn divided into phases. The successful completion of a phase is a precondition for the success of all subsequent phases.
