What is the purpose and conversion recommendation for an ERP-based MDG hub to SAP S/4HANA?
SAP strongly recommends converting ERP-based MDG hub systems to SAP S/4HANA because MDG capabilities in SAP S/4HANA 1809 already go beyond ERP-based MDG 9.2. Treat the project as an S/4HANA conversion first, then adapt MDG-specific content such as custom code, custom objects, business partner integration, and material-number handling.

SAP states that MDG capabilities in SAP S/4HANA 1809 already went beyond ERP-based MDG 9.2, so it strongly recommends converting ERP-based MDG hub systems to SAP S/4HANA. Before conversion, complete the generic S/4HANA conversion checks, use the Simplification List, and adapt custom code, MDG custom objects, and extensions to the new data structures.
