Bausparkasse Schwäbisch-Hall, Germany's largest building society, is replacing its host-based core banking and processing system with a modern standard software solution on an SAP S/4HANA platform. A key milestone in the transformation project, which will take several years to complete, is the transfer of existing business to the new platform. For the building society, the complete, technically consistent data transfer is a critical success factor for the success of the overall project. In addition, the migration effort and the associated costs are a decisive factor for the underlying business case. Based on these considerations, the building society decided to use the paricon data migration framework to ensure a successful data migration. paricon has been dealing with data management and data migration for SAP systems for over 20 years – and has developed the framework based on its many years of experience and has continuously improved it over the years. It provides efficient functions for data extraction, transformation, cleansing and loading, thus enabling efficient and audit-proof data transfer with extremely low implementation effort.
