Cross-field approach

The cross-field approach is a hybrid approach of upgrade and migration methods.

A shell is created using S/4 conversion. Data is transferred via data migration and processes are extended using greenfield fit-gap analysis.

The main advantage of a brownfield-approach approach is the ability to comprehensively adapt processes, organizational structures and systems. Special transformation tools take over the historical data and, if no changes are necessary for individual processes, also selective customizing and enhancements. Such a scenario is particularly interesting for large companies and global system landscapes

with company codes and plants in the 2-3 digit range, where the brownfield-approach is not feasible due to scale and risk. In practice, different scenarios in a sensible and ideally business process-independent sequence and bundling have proven successful for this variant - for example, Finance First, followed by the plants and the company codes.
