Migration to S/4HANA

SAP ECC conversion to S/4HANA

Now it is time to plan the migration to S/4HANA

S/4HANA is the latest-generation ERP system, a successor to SAP ERP (SAP ECC, R/3). 2027 is the last year of system maintenance for SAP ERP. 40,000 organizations have to migrate by then. There may be shortages of specialists to support migration. Therefore, preparations for migration should be made now.

All for One Poland comprehensively supports customers in preparing and carrying out the migration, helping them choose the optimal migration scenario. Our approach combines

  • the competencies of experts in SAP applications and technologies
  • experience from dozens of complex SAP migration projects
  • the unique CrystalBridge platform supporting SAP transformation projects

Find the optimal migration path for your company

Migration from SAP ERP to S/4HANA is possible in various ways, and the choice of the optimal path depends on many factors, including the complexity of the used SAP environment, the type and scope of changes to be made, as well as – to what extent historical data from the old system is to be available in the new one.


Deploy the new system from scratch and start using the new S/4HANA features and technologies, with no historical data available. An additional data migration project is necessary to benefit from reverse analysis.

An optimal approach to transition to S/4HANA for companies that need a completely new set of ERP functions, significantly different from the current system.


The unique approach allows the S/4HANA to be launched with new features, along with the availability of historical data.

Several business and technological transformations can be done in one project, with minimal downtime for business (Near Zero Downtime).

All this is possible thanks to the use of ready-to-use CrystalBridge data transformation platform, which automates the migration activities.



Convert existing SAP functionalities and data to the new S/4HANA technology platform using SAP Solution Manager. In this approach, migration means technical upgrade to S/4HANA and implementation of new functions is carried out in the subsequent steps.

Optimal approach for low and medium complexity SAP environments.

All for One S/4HANA Fitting

The in-depth All for One S/4HANA Fitting analysis allows you to select an optimal, individual migration to S/4HANA strategy, as well as to initially prepare the migration. It is an ideal approach for more complex SAP environments, as well as for organizations that plan to synchronize several SAP-related projects (e.g. system consolidation, transition to S/4HANA and migration to SAP in the cloud).

  • Analysis of SAP environment readiness for migration (Readiness Check)
  • Evaluation of advantages and disadvantages of using different approaches to the migration of a specific environment (implementation from scratch – Greenfield; technical conversion using SAP Solution Manager – Brownfield; an approach of All for One with the use of BLT tools automating migration – Bluefield)
  • Recommendation of an optimal strategy for conversion to S/4HANA along with an estimation of the workload and an initial project schedule
  • Analysis of the impact of external factors on the migration to S/4HANA project (e.g. other planned projects, hosting agreements, interfaces)
  • Test migration (Proof-of-concept – POC) of the production system to the S/4HANA environment (optional)

The result of All for One S/4HANA Fitting is the first step towards future migration to S/4HANA. A several-week project results in a high-level plan of transformation to S/4HANA along with the estimation of the costs and time of the project, as well as the identification of key project challenges.

S/4HANA is based on the revolutionary SAP HANA database technology. The HANA revolution consist in transferring the management of large data sets from disk space to internal memory, which opens up completely new data reporting and analyzing possibilities.

SAP HANA can also be used as a database for the SAP ERP system. SAP ERP customers opt for this migration to use the potential of HANA and also – as part of preparation for ERP migration to S/4 HANA.
