SAP S/4 Hana Migration and Overview

Listen on the go!

According to Gartner, SAP S/4 Hana is a transformational shift for SAP and its users. 

SAP’s next-generation business suite, SAP S/4HANA is much more than an IT tool. It has the potential to transform your organization’s entire business strategy. It enables real-time data-driven decision-making and unlocks the power of breakthroughs such as AI, machine-learning and IoT. Thanks to SAP HANA in-memory data technology, SAP S/4HANA offers unparalleled data processing and visualization capabilities. 

SAP S/4HANA migration is the move from an SAP ECC to SAP’s next-generation SAP S/4HANA business suite (either on-premise, hosted in the cloud or hybrid). 

Why move to SAP S/4HANA 

SAP will no longer support its existing ERP business suite in 2027 – requiring users to move to the HANA in-memory platform. While migrating to SAP S/4HANA is inevitable for SAP customers, the potential costs, complexity, and duration of a migration project may be daunting. 

With over 8,700 customers live on SAP S/4HANA and hundreds more going live every month, now is the time to make your move to our modern, intelligent ERP. 

When it comes to the approach and pace of your migration, your business has options. Re-platforming today – rather than at the last minute – offers even greater flexibility. 

There is no one-size-fits-all approach to migration. You can start from scratch, the greenfield approach, which features a complete redesign of your business processes. A brownfield migration enables you to bring your core ERP structure and historical data with you. A Bluefield migration approach unlocks greater data migration flexibility and speed.

Challenges in migration testing of S/4 HANA: 

  • Obsolete and Consolidated T Codes require knowledge. 
  • SAP FIORI UI Navigation knowledge. 
  • Knowledge of the new S4 hana tables to retrieve data 
  • Test data retrieval techniques will be changed based on navigations 
  • New report’s changes require knowledge 
  • New user interface requires a learning curve 
  • Enhanced business functionalities of S/4 Hana need knowledge 

Since the world is undergoing a digital transformation, it’s high time for SAP customers to migrate from traditional ECC to the latest S/4 Hana application. Migrating to SAP S/4HANA will benefit your business and add overall business value by radically improving your business processes, leveraging your data for improved insights, and driving business agility. 

We cannot deny the fact that customers are habituated to GUI (Graphical User Interface) and using T-Codes (Transactional Codes) from the past few decades and it is not an easy thing for them to migrate to Fiori User Interface all of sudden. Hence, SAP has provided flexible options to smoothen this migration journey. Even though excellent support and guidance is provided by SAP, customers still need a learning curve to adapt to the new enhanced features, UI, and navigations of S/4 Hana. 


Following the best practices for S/4 Hana migration and creating a perfect roadmap will help the customer have a smoother transition. An opt implementation and testing partner’s appointment also gives the best results.
