Greenfield / 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

12. Landscape Transformation

13. | 22-04-2017 | © Atos - Customer13
Landscape Transformation
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

14. System Conversion

15. | 22-04-2017 | © Atos - Customer15

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, …)

Prepare / 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 (!)

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
