Landscape Transformation
▪ Longer timeline▪ Large investment for existing SAP customer▪ Faster adoption of innovations and best
practices (move away from customisation)▪ Opportunity to clean data
▪ Quicker migration realisation▪ Suitable for most customers who have a
single SAP instance▪ Transaction history is retained ▪ Minimal Change Management▪ Custom remediation effort could be high▪ Slower adoption of new innovations

Methodology Overview
Start with POC rehearsal (s)▪ Determine S/4HANA conversion compatibility and
approach, determine likely effort and ‘play book’ for production landscape.
▪ Mandatory functional adaptations only (Technical conversion)
▪ Iterate until success achieved
Migration approach decision point:▪ Conversion▪ New implementation with migration (S/4 Best
Practice Solution)

Prepare PhaseReadiness Check
▪ Which adds on are supported/conflicting?
▪ Which Business Functions are supported/conflicting?
▪ What Custom code needs to be checked / changed?
▪ What data needs to be migrated?
▪ What functional changes are mandatory?
▪ Simplification items (Principle of 1)
▪ What infrastructure sizing requirements will I have?
▪ Which Fiori apps are recommended?
