Migration to SAP S/4HANA – Key Approaches for a Smooth Transition


As businesses strive to stay ahead in the ever-evolving digital landscape, many organizations are opting to migrate to SAP S/4HANA, the next-generation intelligent ERP system. This migration brings significant benefits, including enhanced performance, real-time insights, and streamlined processes. 

While 2027 may hold various significances for different individuals, for those currently working in IT and utilizing SAP systems, it signifies a crucial deadline. SAP has set 2027 as the cutoff date for businesses to migrate to their upgraded system, S/4HANA, after which they will cease to offer support for older systems. Notably, SAP ERP Central Component (ECC) 6.0 will be officially discontinued in 2027. Though this deadline might appear generous, transitioning to S/4HANA is far from a straightforward process, as we will explore in this blog.

A successful migration requires careful planning and consideration of key factors. Here, we will explore the crucial approaches for a smooth transition to SAP S/4HANA. 

S/4 HANA Migration – Key Approaches

Every organization requires a unique S/4HANA Migration Strategy that suits its specific needs. Some opt for a clean start by adopting a new system without any existing data, called a greenfield project. On the other hand, some prefer a complete system conversion, referred to as a brownfield project, as it allows them to maintain their existing business processes without disruption. Additionally, for those aiming to consolidate their existing system landscape into SAP S/4HANA, you have the Selective Data Transition, sometimes referred to as ‘Blue Field’.

S4 HANA Transition Scenarios

The Greenfield Approach

The greenfield approach involves a fresh implementation of SAP S/4HANA, presenting an excellent chance to redefine and streamline business processes while harnessing untapped capabilities offered by S/4HANA. Although this approach does not guarantee immediate operational success, it allows for ample time to make essential adjustments during the system’s implementation phase. 

However, the significant changes introduced in how the system operates can be unsettling. Moreover, the re-implementation process can be arduous and time-consuming, particularly when it comes to change management. Therefore, before deciding to pursue the greenfield approach, ensure that you are prepared for a rigorous and involved re-engineering process.

The Brownfield Approach

SAP recommends the brownfield alternative for customers who wish to transition to S/4HANA while retaining the value of the time and effort invested in customizing SAP ECC to suit their specific requirements. This method involves a conversion process where all business processes are migrated and adapted to the new S/4HANA platform. Compared to the greenfield approach, this method is less disruptive and can be a preferable solution if you prefer to avoid significant operational changes. 

While undertaking a brownfield project, there is a risk of encountering technical issues during and after the conversion process. However, to address these concerns, SAP has specific conversion tools and guidelines designed to proactively mitigate such problems from the outset.

Landscape Transformation

Landscape transformation stands apart from system conversion or new implementations, as it involves a selective migration or consolidation of multiple systems to SAP S/4HANA. 

This approach allows organizations to focus on migrating specific business processes to SAP S/4HANA while keeping the others unchanged. Some organizations choose this route when aiming for the most efficient or quickest return on investment (ROI), such as integrating S/4HANA capabilities into their Central Finance business unit. 

With the appropriate SAP tools, the core methodology can be applied to consolidate both SAP and non-SAP systems. By creating a single, centralized system, this process restructures your business landscape, leading to more streamlined and efficient management.
