Parallel Running

Prove the replacement against live manufacturing work before cutover. For critical ERP and custom systems, parallel running compares old and new results across orders, inventory, production, financial postings, interfaces, and exceptions. Cutover follows defined reconciliation thresholds and accountable approval, not confidence alone.

Order-to-Door™ Digital Transformation Framework

Parallel Running improves the supply-chain flow. It is not a standalone IT project.

Use this capability when the framework reveals that an existing system, record, interface, or unsupported dependency is blocking the people and processes required to fulfill the customer promise.

01

Framework role

Order-to-Door™ maps the people, processes, systems, records, and decisions behind the customer promise before Metrotechs engineers the response.

02

Odoo on AWS system role

Odoo on AWS is the unified implementation path when a new ERP foundation fits; otherwise, Metrotechs protects the approved data, integration, reporting, portal, workflow, and AI boundary around the existing system.

03

AI on Your Data role

AI on Your Data should follow validated records, access, history, and operating ownership—not bypass unresolved legacy dependencies.

01

The Problem

The replacement has been tested, but it has not reproduced the manufacturing results the business depends on.

Modernization problems begin when a critical system is treated as old technology without first documenting the rules, records, interfaces, users, and operating knowledge the business still depends on.

01

What leaders see

Aging systems limit change and concentrate risk.

Support is difficult, integrations are fragile, and ordinary improvements depend on a shrinking group of people.

02

What is actually happening

The business logic is not fully understood.

Important rules, data, reports, workflows, and exceptions live in code, workarounds, and employee memory.

03

What gets worse

A rushed replacement threatens operating continuity.

The new system reaches testing before the team has proved what must be preserved or how each transition will be validated.

02

What Changes

What Parallel Running includes.

For critical ERP and custom systems, parallel running compares old and new results across orders, inventory, production, financial postings, interfaces, and exceptions. Cutover follows defined reconciliation thresholds and accountable approval, not confidence alone.

01

Dual Processing

Run the selected transactions, records, and business scenarios through old and new paths according to a controlled parallel plan. Scope may differ by workflow risk and system capability.

02

Automated Reconciliation

Compare order totals, inventory balances, financial summaries, interfaces, and other accepted outputs using governed rules. Discrepancies route with source evidence for investigation.

03

Exception Reporting

Report discrepancies with affected records, severity, owner, and likely cause categories such as configuration, data, code, timing, or an intentional rule difference.

04

Cutover Criteria

Define measurable reconciliation, exception, performance, control, support, and recovery criteria. Accountable leaders make the cutover decision from that evidence.

05

Gradual Transition

Option to transition user groups or business units incrementally. Start with a pilot group before cutting over the entire organization.

06

Rollback Readiness

Maintain the agreed legacy operating and fallback path during parallel validation. Its capacity, data synchronization, access, and recovery limitations are explicit in the plan.

03

How It Fits Manufacturing

How this capability fits the manufacturing operation.

Legacy ModernizationWhat must be preserved, what can change safely, and whether integration, staged replacement, parallel running, or a smaller intervention is the sound path.
Governance dependencyModernization needs a verified account of what the current system does, who depends on it, how records move, what cannot fail, and how the business will validate each transition.

What must be defined before engineering begins

  • What the manufacturing business needs to change and why.
  • Which systems, records, risks, and readiness gaps shape the work.
  • What should be built, how it fits the architecture, and in what order.

Supply Chain Services and Planning

What to evaluate next.

Follow the dependencies behind this service instead of treating it as an isolated project.

01

Produce or Prepare

Coordinate production, WIP, quality, equipment readiness, changes, and the records behind completed work. This is the Supply Chain service context in which Parallel Running may be used as a delivery capability.

Systems Explained

Use these references to understand the systems that may support this Supply Chain service. They do not redefine the service as an IT project.

01

ERP

Understand the operating records, workflows, and system-of-record boundaries an ERP should own.

Understand the system

Start With the Manufacturing Continuity Objective

Define the smallest sound response and delivery sequence.

Metrotechs determines what the operation actually requires before selecting technology. New material work begins in Launchpad so the evidence, feasibility, architecture direction, priorities, and sequence can be validated before engineering begins.

Metrotechs designs, builds, integrates, and supports the approved solution so demand, fulfillment, and service commitments remain reliable.
A technical request does not bypass discovery. The proposed solution remains a working hypothesis until Metrotechs validates it in Launchpad and maps continuity before build.

04

Delivery sequence

How Metrotechs delivers Parallel Running.

For critical ERP and custom systems, parallel running compares old and new results across orders, inventory, production, financial postings, interfaces, and exceptions. Cutover.

01

Parallel Plan

Define which processes run in parallel, how long, and what success looks like. Identify the reconciliation points and acceptable variance thresholds.

02

Reconciliation Setup

Build automated reconciliation scripts that compare outputs between old and new systems. Define exception categories and escalation procedures.

03

Parallel Execution

Run both systems in parallel for the defined period. Monitor reconciliation results daily and investigate exceptions.

04

Exception Resolution

Diagnose and fix discrepancies -- configuration adjustments, data corrections, or code fixes in the new system.

05

Cutover Decision

When the agreed criteria and approvals are met, execute the cutover. Any read-only legacy retention follows operating, audit, security, licensing, and retirement requirements.

FAQ

Questions to answer before changing this stage.

Straight answers to what manufacturing leaders ask before committing budget to this work.

Duration follows transaction volume, business cycles, financial closes, exception frequency, seasonality, reconciliation evidence, user capacity, and risk. The plan must observe representative work and meet the agreed gates, not a universal calendar target.
