What to Consider?

What Is a System Conversion?

A System Conversion means that you migrate your data from an existing SAP Business Suite system to SAP S/4HANA. This procedure is also known as the “Brownfield Approach.” Think of it as remodeling – while keeping your already shaped IT landscape that fit your business. Instead of tearing down the existing structure and starting again, you’re doing a large-scale renovation.

Your existing ERP system (e.g. SAP ECC) migrates in-place to SAP S/4HANA. And what you’re left with is a mix of old things you’ve grown to like and the new things that didn’t exist when you got started.

In order to make a System Conversion as efficient and smooth as possible, we’ve developed and established what we call our Conversion Factory, which is certified by SAP. You can keep your individual processes and adopt new innovations at your speed – moving to SAP S/4HANA on a fixed schedule and budget.

Why Should I Choose a System Conversion?

1. Because You Can Keep Your Business Processes.

Moving to S/4HANA with your current processes. Processes you already know fit your requirements, provide reliable data quality, and are proven within your daily business. This reduces risk during your transition. Save time and money by keeping your already existing processes.

2. Because You Need Only Limited Business Involvement.

The System Conversion and the data migration result in only slight changes, lowering the requirements of change management. Your processes and workflows will be untouched, which means end users will benefit from the improvements (e.g. increased speed, friendlier UX, and future buy-ins for innovation projects) without the need to undergo extensive retraining. Core users will require only minimal instruction, which saves you time and money.

3. Because You Can Save Time and Budget.

The System Conversion is executed with a so-called “big bang.” The big bang occurs when we prepare your old ERP system for the new platform and then swiftly transition to SAP S/4HANA. This procedure avoids having two parallel system landscapes, which can be both costly and time consuming to support.

System Conversion on Fixed Schedule and Budget

We developed an unique approach, our Conversion Factory, to speed up the System Conversion and streamline the process, allowing you to execute it on a fixed schedule and budget.
