Why You Need to Migrate from SAP ECC to SAP S/4HANA

The latest version of the SAP ECC software suite was released in 2004 and comes packaged with modules for all essential business workflows such as financials, human resources (HR), warehousing, and logistics.

While the legacy SAP ECC application continues to be the core of an enterprise’s digital infrastructure, SAP aims to phase out SAP ECC by the end of 2023, with optional extended maintenance until the end of 2030. The ERP application planned to replace SAP ECC is SAP S/4HANA.

Transform your organization’s entire business strategy into SAP’s next generation business suite SAP S/4HANA. Enable real-time data-driven decision-making and unlock the power of breakthroughs such as AI, machine-learning and IoT. Migrate at your pace and select the best approach for your business.

Select your ECC to SAP S/4HANA Migration Strategy with VC ERP

Greenfield Implementation

This is executed as a fresh implementation of SAP S/4HANA . Customers who are migrating from a non-SAP legacy system or from an SAP ERP system and implementing a fresh system that requires an initial data load. In this scenario, the SAP S/4HANA system is implemented, and master and transactional data are migrated from the legacy system, thus standard data migration tools and content has to be used.and migrates data from your legacy ERP deployments. It is best for organizations looking to take advantage of SAP S/4HANA to re-engineer their processes and return to standard functionality and industry best practices.

Brownfield Implementation

This approach involves converting an existing SAP ECC system directly to S/4HANA. Here, the existing system’s data and configuration are retained, and necessary adjustments are made for S/4HANA’s new data model and other differences. Essentially, the core structure of the legacy environment is preserved, with modifications only as needed to make it compatible with S/4HANA. It’s akin to an upgrade or evolution of the existing system.

Bluefield Implementation

This approach allows a tailored scope between system conversion and new implementation with the flexibility to adapt data and processes in one step. It supports big bang approaches, as well as rollouts, and can be also used to modernize landscape and architecture (e.g. ERP consolidations or move to cloud applications).

This is a consolidation of current regional SAP systems into one global SAP S/4HANA system or a split out of different parts of a system: customers who want to consolidate their landscape or carve out selected entities (such as a company code) or processes into a single SAP S/4HANA system.

Lift and Shift

This approach is best suited when moving from On-Premise scenarios to RISE with SAP S/4HANA Private Cloud environments. “Lift and Shift” implies taking the existing system (in this case, SAP ECC) and trying to move it as-is to the new environment (SAP S/4HANA Cloud – RISE). A brownfield approach involves converting the existing ECC system to S/4HANA, retaining the historical data, and adjusting for the new data model and other changes. It’s about evolving or converting an existing system rather than starting fresh.This approach makes the most sense when you are supported by the RISE with SAP offering.

Custom Code Migration for SAP S/4HANA Services

Custom Code Migration is part of the system conversion process from the classic SAP Business Suite running on any database to the SAP S/4HANA system. In the context of this system conversion, custom ABAP source code needs to be adapted, since a lot of SAP code within SAP S/4HANA gets simplified and in some cases gets changed in a non-compatible way.

When it comes to custom code migration from SAP ECC to SAP S/4HANA, there’s a tool known as the “Custom Code Migration” app, which is part of the SAP Fiori suite. Additionally, SAP provides the “SAP Readiness Check” tool and the “ABAP Test Cockpit” (ATC) for code checks and adjustments. At VC ERP, we are well-versed with all available tools, approaches and strategies.

We have demonstrated expertise in enabling ecc to s4hana conversions through the custom code migration process which consists of the preparatory analysis (custom code scoping and custom code analysis) and the adaptation of the custom code (custom code adaptation) after the technical system conversion.
