Buckle up as we explore the world of SAP S/4HANA migration and equip you with essential knowledge for your upcoming journey. It’s vital to see this as more than a simple update.
Critical Questions to Address
Kickstarting your migration means tackling several key questions:
- Goal Setting: What’s SAP S/4HANA’s envisioned role in your landscape? Is it for a proof of concept or immediate production? Can it serve as a chance to refine your processes?
- Operation Mode: Do you plan to run SAP S/4HANA in-house, via hosting, or as a SaaS?
- Current State: How’s the data quality in your current system? How extensively is SAP standard used? Are there custom enhancements?
- User Layout: How are your users distributed? Who stands to gain from the SAP S/4HANA migration?
- Business Utilization: What business scenarios and transactions will be used? How are these distributed across your users?
- Timeline: What’s your project timeline? What are the critical milestones?
- Support: What support will you need? What’s your budget? What services will be outsourced, and what can be handled internally?
SAP S/4HANA Implementation
Understanding SAP’s digital core paves the way to maximizing SAP S/4HANA’s potential value. The deployment should encompass both technical and process-oriented aspects.
1. Technical Implementation
- Migrate the database to SAP HANA
- Replace program code
- Adapt data models to the SAP S/4HANA data model
- Implement the frontend server for SAP Fiori interfaces
- Adjust existing custom code
2. Process Deployment
- Adapt existing business processes mapped in the system
- Introduce new applications
- Perform comprehensive change management steps
A Three-Phase Migration
Split your migration into three key stages:
1. Preparation
- Analyze existing business processes and compare them with SAP S/4HANA innovations
- Identify necessary integration scenarios
- Perform pre-checks in the source system
- Implement necessary preparatory conversions
2. Technical Implementation
- Install SAP S/4HANA, SAP HANA database, and applications
- Adapt technical infrastructure and customize
3. Process Adaptation
- Adapt custom programs in SAP S/4HANA
- Develop new or enhanced business processes leveraging SAP S/4HANA innovations
- Adapt integration scenarios and customize SAP Fiori interfaces
The trade-off
There’s a balancing act in SAP S/4HANA migration. Retaining more of the original system simplifies technical migration but may limit SAP S/4HANA’s potential benefits. Thoroughly analyze the trade-offs considering usage type, operating model, total ownership cost, and target landscape.
SAP advocates for the SAP Activate methodology, featuring six stages: discover, prepare, explore, realize, deploy, and run. This blog post focused on the discovery stage, which defines priorities, target architecture, business case optimization, and readiness check – laying the groundwork for a successful migration.
