SAP S/4HANA Migrations

Migrating to SAP S/4HANA can bring numerous benefits, such as improved performance, real-time analytics, enhanced user experience, and simplified business processes. However, like any complex migration, it comes with its fair share of challenges. Our experts help you to master those

8 typical Challenges during Migration


Data Complexity

SAP S/4HANA operates on a different data model and database structure compared to older SAP versions. Migrating and cleansing data can be a significant challenge, especially if the data is poorly structured, contains duplicates, or is outdated. Data conversion and harmonization are critical to ensure a smooth transition.


Integration with Third-Party Systems

Enterprises often have multiple interconnected systems, and integrating them with SAP S/4HANA can be complex. Ensuring seamless data flow between SAP S/4HANA and other applications is essential to maintaining business continuity.


Project Complexity and Duration

SAP S/4HANA migrations can be complex, particularly for large enterprises with extensive data and system landscapes. The migration process can be time-consuming, leading to business disruptions during the transition.


Skill Gaps

Migrating to SAP S/4HANA may require new skill sets that existing IT teams may not possess. Organizations might need to invest in training or hire specialized consultants to handle the migration effectively.


Custom Code Adaptation

Many organizations have custom code, modifications, and enhancements in their existing SAP landscape. These customizations might not be compatible with SAP S/4HANA. Companies will need to assess and adapt their custom code to be compatible with the new system, which can be a time-consuming and costly process.


Business Process Reengineering

SAP S/4HANA offers numerous process improvements and new functionalities. However, to fully leverage these benefits, organizations may need to reengineer their existing business processes. This requires careful planning, stakeholder involvement, and change management to ensure successful adoption.


Change Management and User Adoption

Introducing a new system can be met with resistance from end-users. Adequate change management strategies and user training are vital to ensure employees embrace the new system and utilize it effectively.



Migrating to SAP S/4HANA can be a significant financial investment. Besides licensing and implementation costs, companies should consider the expenses associated with data cleansing, custom code adaptation, training, and infrastructure upgrades.

To address these challenges successfully, organizations should conduct comprehensive planning, engage stakeholders, involve subject matter experts, and partner with experienced SAP migration consultants or service providers. Early preparation and clear communication are key to a successful SAP S/4HANA migration.
