“New Implementation”, which is as the name implies starting afresh, or upgrading SAP ECC 6.0 using “System Conversion”, which allows the migration without re-implementation and without major change or disruption to existing business processes.
Smooth migration of SAP Application to AWS Cloud
A system conversion preserves your original system, including data, processes, and custom code. However, the value of retaining these should be assessed. Some of it may be obsolete such as custom code written for reports that is now readily available to the user as analytical reports. This was certainly the case in our approach.
Not everyone will agree to abandon their custom code and processes that they have developed over years. This approach is best suited for those. This approach cannot be used to migrate to SAP S/4 HANA Cloud.
With a system conversion, you move/convert your existing SAP ERP system into an SAP S/4HANA system. This one-step procedure includes:
- A database migration to SAP HANA 2.0 from your current SAP ERP DB.
- Conversion of data from the SAP ERP data model to S/4HANA data model.
- An upgrade, that replaces your SAP ERP application code to SAP S/4HANA application code.
