Case study · From the Pluris libraryReceipt no. 7147
What sucked
The enterprise faced SAP ECC end-of-support and had to migrate to S/4HANA.
The core risk was silent regressions, where downstream processes break or diverge without anyone noticing during the transformation.
What they built
Tensile applied a reference-design approach to prove equivalence between an enterprise's legacy SAP ECC system and its migrated S/4HANA environment. Real production data is replayed through both and the outputs compared, providing evidence that nothing regressed before go-live.
What changed
Equivalence proven
A reference design validates that the old and migrated systems produce the same results.
Production data replay
Real production data is replayed to catch regressions before cutover.
Deadline-driven confidence
Addresses the SAP ECC end-of-support deadline with evidence that nothing regressed.
