Parallel Run: Reconciling Old and New WMS Data During a One-Month Cutover
Bottom line up front: run old and new WMS in parallel for at least two weeks, ideally four, with inventory variance tolerance at 0.5% and zero tolerance on order status. An implementation consultant's five-step daily reconciliation method, a three-tier variance triage table, the three kill signals for the legacy system, and a go-live-eve checklist — drawn from 30+ cutovers including a Dallas auto-parts warehouse that lost roughly $110,000 by cutting over after only 7 days.
