SAP ECC to SAP S4 HANA Migration Alternatives

When moving from SAP ECC to SAP S4 HANA, a variety of issues can arise. To determine the most appropriate migration path for S/4 HANA, it’s critical to understand and evaluate the deployment model, such as cloud (SaaS), HEC (IaaS), or on-premise), maturity level (S/4HANA Finance or Full S/4HANA Enterprise Management), and functionalities and modules used in the current scenario.

Determining the migration scenario is critical since it allows you to set the scope, team size, and project evaluation based on this information (bid amount). Furthermore, this identification aids in the direction of the following actions:

  • What will be the Magnitude of the Work, the scope
  • What is the number of phases of this project?
  • What requirements will define the size of the team
  • What is the value of the project

SAP S /4HANA is the business suite of the future. SAP HANA is the most advanced memory platform available today. With SAP Fiori user experience (UX) and a new role-based user experience approach, the solution employs modern design ideas. Companies who switch to SAP S/4HANA benefit from continual application advancements such as:

SAP HANA memory platform-specific application optimizations

SAP S/4HANA improves the application to take full advantage of the SAP HANA database’s capabilities. We delete aggregates, for example, to lower the data footprint.

Responsive User Experience Design

With SAP S/4HANA, SAP designs the application with the latest role-based user experience (UX).

Unifying functionality in the core

With SAP S/4HANA, SAP removes redundancy, thus providing functionality for a purpose. It helps companies operate seamlessly in the digital economy, thereby including topics and principles such as the Internet of Things, Big Data, business networking and mobile-first.

SAP ECC to S4 HANA migration scenarios

Scenario 1: New Implementation

Customers transferring from a legacy non-SAP system or a SAP ECC system to a new system that requires an initial data load are considered new SAP S/4HANA implementations. Standard data migration tools and content must be utilised in this case since the SAP S/4HANA system is deployed and the master and transactional data are migrated from the legacy system.

Scenario 1: System Conversion

Customers who want to upgrade their present SAP ECC system to SAP S/4HANA (elevator and shift). If the customer is not currently using SAP HANA as the underlying database, this scenario is technically based on Software Update Manager (SUM) with Database Migration Option (DMO).

Scenario 3: Landscape TransformationSystem landscape transformation allows customers to consolidate their landscape or construct specified entities (such as a company code) or processes in a single SAP S/4HANA system by combining current regional SAP systems into a global SAP S/4HANA system or by splitting separate elements of a system.
