Engineering an AI-Powered Leap From Legacy to Oracle Fusion

Calfus engineered an AI-powered leap from two decades of Dataworks history to Oracle Fusion, replacing what is typically a slow, manual data conversion with automated, AI agent–driven migration cycles. Pairing disciplined change management with Transformate, the AI-driven migration engine within Calfus’s Aetherion suite, the team delivered a validated Fusion rollout for MI Windows and Doors in a journey that piloted with Milgard and Western Architectural Openings — setting the template for MITER Brands’ portfolio-wide Fusion journey, including PGT Windows and Doors and Anlin

Deployed Transformate, Calfus’s AI-powered migration tool, to automate the loading of customers, suppliers, AP invoices, AR invoices, POs, and PO receipts — compressing customer conversion from 1 week in Phase 1 to a single weekend in Phase 2.
Cut manual effort and back-and-forth with business teams by automating data mapping, validation, and reconciliation during conversion cycles.
Ran iterative testing cycles with business stakeholders to confirm data accuracy and readiness ahead of go-live.
