The Challenge
The client ran a heavily customized SAP ECC system supporting 200+ stores. With SAP's ECC end-of-support approaching, they needed to migrate to S/4HANA while maintaining business continuity during peak retail seasons.
Our Solution
Inola's SAP practice led a selective data transition approach — implementing S/4HANA as a new system while selectively migrating master data, open transactions, and three years of historical data. The migration was phased to avoid peak seasons, with parallel running during the cutover period.
