H4S4 Migration Package

Many companies use SAP ERP HCM as their central platform for HR processes – often deeply integrated and highly customized for years. However, maintenance will end in 2027 (with extended maintenance available until 2030). Organizations now face the strategic decision of how to future-proof their HR landscape. With our H4S4 Migration Package, we support the transition from SAP HCM to S/4HANA.

Our Offering: H4S4 Migration Package

H4S4 is the recommended migration solution for existing SAP customers running SAP HCM, embedded within the S/4HANA ecosystem. H4S4 provides a modern technology platform, improved integration capabilities, and connectivity to SAP SuccessFactors. By migrating to H4S4, companies ensure maintainability and continuous development beyond 2030. The goal: H4S4 combines stability in core HR processes (PA, OM, PT, PY) with the flexibility to introduce innovation, automation, and digitalization in parallel. But how do you get there?

Scope of Service

Our approach to H4S4 migration is based on the SAP Activate Methodology: in six phases, from Discover to Run, we guide our customers through a series of structured steps.

• Discover: Project initiation, definition of the target vision for the HR system landscape (on-premise / hybrid scenarios / cloud), and establishment of the project team.
• Prepare: S/4 Readiness Check, Custom Code Check (ATC), interface analysis.
• Explore: Definition of work packages, creation of the project plan, identification of new developments and enhancements.
• Realize: Configuration and implementation, development of extensions (SAP BTP, Fiori), documentation and training.
• Deploy: Data migration and final testing.
• Run: Hypercare and ongoing support.

Our recommendation: Take a step-by-step approach to the H4S4 migration. This ensures transparency regarding effort and risks, and provides a solid basis for decision-making on the next steps. We begin by defining the HCM roadmap – the strategic target vision for the HR IT architecture. Then, with the H4S4 Starter, we conduct a pre-project for the migration, covering the Discover, Prepare, and Explore phases. In the final step, the H4S4 migration takes place, including technical implementation, data migration, integration, and go-live (Realize, Deploy, and Run phases).

Business Benefits

Migration projects take time: existing custom developments, interfaces, and country-specific requirements need to be analyzed and, if necessary, migrated or rebuilt. Those who start late risk resource and expertise bottlenecks – our H4S4 Migration Package is the perfect way to make the transition. It also helps you avoid the increased costs associated with staying on legacy systems (Extended Maintenance). One thing is clear: HR must evolve from a purely administrative function to a strategic business enabler. But which tool setup is right for that? H4S4, SuccessFactors, BTP – how can these systems be orchestrated effectively? We’ll show you how.

It’s time for companies to realign their HR. Let’s talk about our shared journey toward the future of HR together.
