The build
Legacy AS/400 cutover
01 — The Problem
What was breaking
A 22-year-old AS/400 system held two decades of operational data and ran the entire plant. A wrong move at cutover meant stopping the line.
02 — The Approach
What we engineered
We ran a phased migration with continuous reconciliation, mirroring the old system until every record matched, then cut over module by module without interrupting production.
03 — The Outcome
What changed
100% data integrity, zero line stoppages, and a modern core the team controls.
