SAP S/4HANA Migration Options
Although experts at SAP and other tech leaders can reel off quite a few ways of handling a switch to SAP 4/HANA, three are more commonly recommended than the others.
1. Greenfield Approach
One option isn’t really a migration option. Instead, it’s an implementation of S/4HANA from the ground up.
“Greenfield” is a term adopted from architectural and environmental engineering that means starting fresh on land that has no previous construction. For S/4HANA specifically, it means either migrating data only or no migration at all. You retire legacy customizations and work to streamline processes.
2. Full Migration
A full migration approach is a complete conversion of an existing SAP system to SAP S/4HANA, a method often referred to as “lift-and-shift.”
This scenario involves using SAP Software Update Manager with a database migration option for any enterprise not using SAP HANA as their database. To address application customization, enterprises can use SAP cloud and SAP partner development tools.
3. Hybrid Migration
In a hybrid migration, organizations need to analyze the current SAP system and identify the customized applications, functionality, and interfaces that are not part of the core.
Before the migration, enterprises can use a low-code platform to develop the non-vanilla pieces and applications used by the system. By doing that work in advance, the SAP core is kept clean to make the migration easier.
Afterwards, your business is using S/4HANA for what SAP does best—enterprise resource planning—and other apps for what it doesn’t do best.
