In the dynamic world of SAP and software development, enterprises are presented with an opportunity to enhance their performance and stay competitive by transitioning from SAP ECC to S/4HANA.
This transformation is a significant milestone in updating existing business processes, and it is crucial to approach it with confidence and careful planning. In this blog post, we’ll provide a concise overview of a Brownfield implementation and migration to S/4HANA.

What do we mean by ‘Brownfield’ implementation?
The ‘Brownfield’ approach, also called system conversion, involves transitioning existing systems, typically SAP ECC, onto the S/4HANA platform while preserving pre-existing data, processes, and software development customizations.
For organizations with large and complex SAP landscapes, Brownfield implementations can be a lengthy journey.
Unlike ‘Greenfield’ implementation or a ‘Hybrid’ approach, Brownfield S4HANA transformations involve technical system conversion, custom code reviews, data cleanup, and a “Big Bang” cutover. These complexities therefore necessitate thorough planning and execution of Brownfield development so the system makes operational sense.
The challenges slowing progress
Brownfield projects demand meticulous preparation and knowledge. For example, dual maintenance must be managed precisely to avoid unpleasant surprises during the transition phase of existing business.
The “Big Bang” switchover approach, common in Brownfield development, carries significant business risks. Any missteps can lead to operational collapse, extensive costs, and resource allocation issues.
All of these challenges result in delays. In our research – featured in this eBook – we found that the top three factors for delay were:
- Not having carried out the necessary preparations for the new system (75%)
- Not having the right internal skills, understanding, or resources (50%)
- Not feeling the urgency due to the length of time until the S/4HANA deadline (50%)
The main considerations for a Brownfield implementation
Upgrading existing systems is a critical step in the system conversion to S/4HANA. However, for organizations taking the Brownfield approach, upgrading current SAP systems can be challenging, especially if they are far from the latest ECC version.
Automation plays a crucial role in managing the complexities of this process, enabling teams to handle changes effectively and ensure that new system improvements are executed smoothly.

A Brownfield implementation essential: automation
Migrating to S/4HANA presents opportunities for innovation and development, but it’s a massive undertaking. Manual, spreadsheet-based approaches can slow down the transition and introduce unnecessary risks.
Automation technology is the key to a smooth Brownfield S/4HANA transformation, offering faster delivery, reduced costs, and minimal errors in implementation.
Basis Technologies offers automation solutions that have resulted in a 50% reduction in change delivery costs, a 95% reduction in manual effort, 50 times faster delivery of new features, and a 70% reduction in downtime.
Transitioning to S/4HANA is a critical business development move. With careful planning and the right automation tools, organizations can navigate this transformation successfully, unlocking improved compliance, simplified processes, and a competitive edge while minimizing any risk and costs.
If you’re considering this transformation in business and software development, Basis Technologies can provide the support you need at every stage of your S/4HANA journey.
