# S/4HANA migration - Link: https://www.agilita.de/en/s-4hana-migration/ - Published: 2019-04-08T13:11:04+01:00 - Author: Julliana Zuellig – honest. According to SAP release planning, every existing SAP ERP solution must be migrated to S/4HANA by 2027. Take advantage of our experience and make this system transformation as uncomplicated, secure and resource-saving as possible. One thing is clear, only the free technical check on your SAP system does not put you in a position to decide on feasibility, effort and procedure. That’s why we are developing a roadmap for them that has it all. The S/4HANA Readiness Check gives you an overview of S/4HANA and the underlying system architecture. Our team uses the “Simplification List” and the “Compatibility Scope” to create a recommended course of action for each item. You will also benefit from an introduction to SAP Fiori (SAP Fiori Launchpad) and S/4HANA SAP Best Practices. The result is a project plan for the migration to S/4HANA with the fields of action, as well as a budget plan. Fields of action for process optimizations as well as the optimization potentials through the use of the new technologies or the return to standard functions (BPML definition) are critically examined in order to be able to clearly assess the Greenfield and Brownfield scenarios. You receive both a rough overview of the system and application architecture and access to the results of the ERP system scan (HTML access).

According to a report by IDC, 40% of organizations are concerned that the key challenge in migrating to SAP S/4HANA is migrating of the custom code will be. Therefore, they should use the time and opportunity before the changeover as a way to simplify the existing systems and their extensions, and modifications. We find the critical points for you and help you to check the existing custom ABAP code in SAP ERP. The goal is to remove all unnecessary custom code to save effort. ![](https://www.agilita.de/wp-content/uploads/2019/04/handshake_orange.jpg) The migration to SAP S/4HANA requires some preparation in existing SAP systems. In order to make the migration successful, they should deal with the prerequisites early on. Another field of action that can be addressed at an early stage is the central business partner. This is because an essential part is the changeover to the central business partner as an alternative replacement for the classic debtor and creditor. Trust our years of experience in this functionality from industry solutions that have always had this feature. We help you to ensure that you not only implement this function technically, but that the data quality is also correct from the migration onwards. This solution can be implemented in advance in the Business Suite and save valuable time during a later changeover. If all preparations have been made and there is a central ERP that is well structured and cleanly set up and in which there are no inconsistencies, the migration is then very quick and easy. The time schedule for the path to SAP S/4HANA is customer-specific and ranges between 6 and 9 months. If you don’t want to switch to SAP S/4HANA immediately with all the consequences, you can approach the change for your company a little more gently with a two-step process. The first step here is to switch to SAP Business Suite on HANA. This means that only the database will change for the time being – for end users, everything will remain the same for the time being, apart from a significant increase in speed. The second step, i.e. the conversion to SAP S/4HANA, can then take place somewhat later in a downstream project. ![](https://www.agilita.de/wp-content/uploads/2018/03/compass_grau.jpg) ![](https://www.agilita.de/wp-content/uploads/2018/03/transfer-1_orange.jpg) One thing is certain, this migration clears the way for their new, digital ERP solution from SAP.
