From ECC to S/4HANA: A guide to a successful migration!

In the current digital transformation landscape, organizations are seeking solutions that optimize their internal processes, improve data control, and streamline their operations.

System Applications and Products in Data Processing has played a crucial role in automating routine tasks, such as report generation, which once required manual effort. Furthermore, robotic process automation further boosts the efficiency of daily activities.

As the digital landscape evolves, SAP is also undergoing a transformation to align with emerging trends, such as Artificial intelligence the Internet of Things (IoT), blockchain, and data analytics. This means that software users will need to migrate from SAP ECC to S/4HANA by the stipulated deadline of 2027. Failure to migrate could result in increased maintenance costs and the loss of Enterprise Support.

S/4HANA, compared to its previous version, was developed to adapt to organizations' current operational model. It offers greater flexibility regarding changes, acquisitions, and the integration of new sales channels. The growing need for this flexibility is evident as companies expand into new markets and integrate products from smaller brands through acquisitions. S/4HANA allows companies to maintain these acquisitions in a public SAP cloud environment, eliminating the complexity of integrating them directly into the system's core.

Additionally, S/4HANA offers a significant improvement in terms of speed. Through intelligent data design, the system reduces data redundancy and aggregation, resulting in faster analyses and insights. Integrating business transactions and analytical capabilities within the same system streamlines decision-making and process execution, consolidating all these functionalities into a single application and a single source of information. In addition to these benefits, the migration is associated with a significant reduction of 30% in operational costs, a saving of 20% in inventory, and a remarkable acceleration of 50% in billing processing times.

Migration Models for SAP ECC to S/4HANA

The success of the migration largely depends on the chosen strategy. Three main models emerge as options: Brownfield, Greenfield, Bluefield/Shell Conversion.

• The Brownfield approach preserves all historical and configuration data, making it suitable for young companies or those already aligned with the SAP standard. Renowned companies, such as Pague Menos, Localiza, Safra, and Raia Drogasil, used this model, representing 73.5% of migrations, according to a survey conducted by Mignow.
  
• On the other hand, Greenfield involves a complete installation and configuration, allowing for testing innovations and third-party systems. This model is found in 5.9% of migrations.
  
• For complex companies with sophisticated structures, the Bluefield or Shell Conversion model stands out as the best alternative. This model combines characteristics of both Brownfield and Greenfield models, allowing the organization to select which data to leverage.

With this approach, it's possible to start SAP from scratch and run separate processes for different business codes, optimizing system downtime and including specific data in the conversion. Companies like Centauro and Grupo Petrópolis chose this model, which also accounts for 5.9% of migrations, according to the survey.

The survey also indicates that 14.7% of respondents are unfamiliar with the models or don't know which one to use for their migration. To choose the best migration option for each organization, an internal study is recommended, involving databases, departments, employees, and an analysis of the company's system itself, which includes the organization's magnitude, system versions, size, integrated plugins, amount of customized code, and the so-called "Z's," which are specific organizational extensions that will not use SAP. This stage, called assessment, is a self-discovery process for the company, is part of the pre-project phase, and is fundamental for a more effective migration with a lower error rate.

Selecting the appropriate migration model requires a comprehensive internal evaluation, taking into account factors such as the organization's size, current system configurations, customizations, the amount of customized code, and company-specific extensions. This evaluation process is crucial for minimizing errors and ensuring a successful migration.

Another crucial decision involves choosing between a physical data center and migrating to the cloud. SAP offers the solution Rise with SAP, which enables the adoption of cloud services, such as Google or Microsoft. The choice between migration models and infrastructure options can influence process efficiency and the results achieved.

Highlighting the importance of the company responsible for the ECC to S/4HANA migration is imperative. A personalized analysis is essential to guide the organization in selecting the ideal strategy, from the assessment phase to decisions regarding partial or total data migration, as well as infrastructure choice. These factors directly impact the success of the migration, affecting both the time and costs involved.
