Migration & Transformation
What is System Conversion?
The technical process of converting an ECC system to S/4HANA, including database migration if needed and data conversion.
Steps include prerequisite checks, CVI, custom code adaptation, SUM execution, and finance data migration. Mock conversions on production copies validate runtime and quality. It is the technical core of a brownfield approach.
