New System Installation Overview Source: http://help.sap.com/ Description: ▶ Pre-defined migration objects & Best Practices available in a guided process ▶ Reengineering and process simplification based on ready-to-run business processes and reference solution delivered with the product Tools: ▶ SWPM (Software Provisioning Manager) ▶ SAP Data Services (on-premise) ▶ SAP Landscape Transformation (cloud) ▶ SAP S/4HANA Migration Cockpit (Initial data load from source system)
/ New System Installation Overview Source: http://help.sap.com/ Guided Configuration: • Data migration objects proposed based on the selected business scenarios • Customers migrate data using a template based approach
Overview Source: http://help.sap.com/ Description: ▶ Value-based migration: selective data transformation allows a phased approach focusing the first SAP S/4HANA migration phase on parts of the business with highest ROI and lowest TCI ▶ Agility: stay on current business processes but move gradually to SAP S/4HANA innovations (Move to SAP S/4HANA at your own pace!) ▶ TCO reduction: system and landscape consolidation with harmonized/ simplified processes and unified master data lead to lower cost of operations Tools: ▶ SAP Landscape Transformation
/ System Conversion Overview Source: http://help.sap.com/ Description: ▶ Database, SAP NetWeaver and application transition in one step ▶ Migration without reimplementation ▶ No disruption for existing business processes ▶ Re-evaluation of customization and existing process flows Tools: ▶ SUM DMO (Update, Upgrade, combined Update & Migration, System Conversion, …)
System Conversion Maintenance Planner Source: http://help.sap.com/, TECHED ITM213 The Maintenance Planner: ▶ Simplifies landscape maintenance process to update, upgrade and install systems ▶ Define changes (based on your landscape data in customer profile) ▶ Source system is checked for business functions and add-ons. If there is no valid path for the conversion (for example, the add-on is not released yet), Maintenance Planner prevents the conversion. ▶ In case of valid conversion path: calculates all files and the stack configuration file that the Software Update Manager (SUM) requires ▶ Is mandatory for the SAP S/4HANA Conversion (!)
System Conversion Pre-Checks Source: http://help.sap.com/, TECHED ITM213 • Implement System Conversion Check Report (Note 2182725) needs to be run in all systems being converted - SUM also executes this report • Output of items which need to be completed before system is ready for conversion, e.g. used Add-Ons and Business Functions not supported in S/4HANA 1610 yet
System Conversion Custom Code Migration Worklist Source: http://help.sap.com/ • Check Custom code against S/4HANA Simplification Database Content • Get deep insight into needed adoptions of custom code for S/4HANA • Basis for estimation of efforts of S/4HANA conversion • Results might be used to find obsolete code for cleansing of custom code • In many cases it is possible to prepare for the system conversion already by adopting the future target capabilities in the classic SAP Business Suite
System Conversion Simplification List Source: http://help.sap.com/ What happens to individual transactions and solution capabilities? Detailed functional-level descriptions of required changes to individual transactions and solution capabilities in SAP S/4HANA. Guidance on the activities customers need to complete before, during, and after the conversion to SAP S/4HANA.
