SAP S/4HANA System Conversion

Benefit from the Brownfield Approach for Transition to SAP S/4HANA

You may already have an IT landscape that performs in conformity with your needs. However, you can still improve it by moving to SAP S/4HANA, while also maintaining your existing structure and processes. The Brownfield Approach enables a smooth transition without exceeding the budget or going beyond the schedule.

What Is a System Conversion?

If you are already using an SAP Business Suite system, all data on this system are migrated to SAP S/4HANA with the System Conversion method. Rather than building a brand-new system, this method remodels the IT landscape, and thus is also called the “Brownfield Approach”. With this method, the ERP system (for instance SAP ECC) is largely renovated on SAP S/4HANA. In other words, your system maintains the previous processes that proved useful to your business and reinforces it with new qualities of SAP S/4HANA.

Since migration is not an easy process, NTT DATA Business Solutions has developed the SAP-certified Conversion Factory to ensure an efficient and smooth conversion. With this solution, you can convert the system in your own pace, without the need for extra time or budget.

Why Should I Choose a System Conversion?

1. Because You Can Keep Your Business Processes.

If you have processes and structures that meet the requirements of your business and you do not wish to eliminate them, you can move to SAP S/4HANA through System Conversion. Thus, you can continue to use existing benefits such as reliable data and conformity with your daily business. This method avoids risks during transition and saves time and money.

2. Because Limited Retraining Will Be Enough for Your Team.

Are your teams already familiar with the system and use it efficiently? Then, they will not need detailed trainings for the new landscape because the System Conversion method maintains business processes. Thanks to this method, you can achieve improvements in speed, UX and future-oriented investments, while also keeping your processes and workflows. Minimum training also means time and cost savings.

3. Because You Can Save Time and Budget.

In the System Conversion method, the new landscape is generated on SAP S/4HANA and when everything is ready, your existing system is migrated through a “big bang”, which means a fast transition. As there will be no parallel systems running at the same time, you will save time and money.
