Multi-Client WMS Migration Quality Checklist

Use this checklist to protect SLAs during multi-client or multi-tenant WMS migrations—before cutover, during stabilization, and into steady-state maintenance.

Pre-Flight Quality Checklist (Before Build)

Build & Configuration Quality Checklist

Testing Quality Gates (Don't Skip These)

Cutover Gate (Green = You Can Move)

Key Risks (Multi-Client Migrations)

Risk: "Wave contamination"

One client's exception handling (labels, routing rules, EDI mapping) accidentally impacts others. Prevent with strict configuration isolation and regression tests.

Risk: Inventory mismatch after cutover

Small conversion errors become big service failures. Require reconciliation rules, cycle counts, and quarantine workflows for variance resolution.

Risk: Carrier cutoff/timezone mistakes

Cutoff logic and local time settings can silently break on-time ship. Validate in production-like settings and monitor day-one manifests.

Stabilization & Hypercare Expectations (Vendor ↔ Org)

Hypercare is a defined post–go-live window with extra resources, run like a command center, with clear roles, SLAs, and exit criteria.

Hypercare Operating Model (Recommended)

Vendor ↔ Org Responsibility Split (RACI Starter)

Activity Org (3PL) Vendor Shared Notes
L1 Support (floor questions, process clarifications) R/A C Use super users; keep vendor out of routine questions.
L2 Support (config, workflows, integration triage) R R Joint triage; vendor provides fix guidance and patches.
L3 Support (defects, performance, vendor code) C R/A Clear defect process and hotfix windows.
KPI monitoring & daily reporting R/A C Start with a short KPI set; expand later.
Hypercare exit decision A R Exit only when criteria hold for 5–10 business days.

Exit Criteria (Don't Leave Hypercare Until…)

Long-Term Maintenance (Stability Over Months)

Want this implemented as a real program plan?

We'll translate these gates into a cutover plan, hypercare model, and measurable stability targets—without slowing down operations.
