Why Migrate from SAP ECC to S/4HANA?

Migrating from SAP ECC to S/4 HANA is not just another upgrade; it’s a strategic decision and one that could impact the effectiveness of the business in positive and negative ways. These are a few of those reasons why an S/4HANA transition is a must:

Real-Time Analytics: S/4HANA – With S/4HANA, the real-time processing world is changed by real-time analytics capabilities, allowing businesses to more quickly and confidently make decisions from their data.

Simplified Architecture: One of the major benefits of S/4HANA for partners and customers is a simplified data design that removes some of the “complexity” that typically riddles their ECC systems.

Improved User Experience: With the modern look & feel and enhanced user experience with SAP Fiori, the user interface across all devices has never looked this good before.

Advanced Automation:  S/4HANA includes automation capabilities by embedding machine learning and AI into business processes to minimize manual work.

Scalability: As an application running on the SAP HANA in-memory database, S/4HANA can handle the kind of massive processing load that growing businesses require without having to worry about infrastructure.

Cost Efficiency: One in five businesses agree that the cost of operations will decline under S/4HANA, as the IT-dreaded service and support required would be minimized.

Steps for SAP ECC to S/4HANA Migration

Migrating from SAP ECC to S/4HANA requires careful planning and execution. Below are the steps to ensure a successful migration:

1. Assess Your Current ECC Environment

• Before beginning the migration, do a comprehensive analysis of your SAP ECC environment so that you know your current environment, customizations, and configurations.
• This phase will help determine which components should be migrated, customized, or archived.

2. Choose the Right Migration Approach

There are generally three main paths to move from SAP ECC to S/4HANA:

• Greenfield Migration: Begin from scratch with a new S/4HANA system. This is ideal for businesses that wish to re-engineer processes and have few legacy systems.
• Brownfield Migration: Move the current SAP ECC into an S/4HANA installation. It’s perfect for companies that wish to maintain their existing setup and company processes.
• Hybrid Migration: This combines both Greenfield and Brownfield approaches, and allows you to migrate your core business processes and data, but retain some of the existing legacy system.

3. Data Migration from ECC to S/4HANA

• Data migration is one of the most important activities in the ECC to S/4HANA migration. This means moving data from SAP ECC to S/4HANA and ensuring the integrity and accuracy of that data.
• Data pasteurization and validation are part of the migration process so that incompatible data will not get imported into the new system.

4. Perform the Technical Conversion

• This step includes the transition to your old, inadequate system with all the customizing that is currently required so that it will work with S/4HANA.
• The technical conversion can be facilitated by leveraging capabilities provided by SAP Software Update Manager (SUM) and SAP S/4HANA Migration Cockpit to minimize the impact on business processes.

5. Test the System Post-Migration

• Following the move, do a thorough test to verify that the new S/4HANA system is working properly.
• Verify and check the migration for functions, integrations, security, performance, etc.

6. Go Live with S/4HANA

• Stand up – S/4HANA In a second phase, then go live finally with S/4HANA. Make sure your crew has the training and capability to work in the altered conditions.

7. Post-Migration Support and Optimization

Continue to support and optimize long after going live. Keep an eye on your system and make changes.
