What leaders see
Work keeps moving, but only because people fill the gaps.
Teams rely on manual checks, side files, rekeying, status meetings, and individual knowledge to keep the process alive.

Parallel Running
Prove the new system works before you switch. The scariest moment in any migration is the cutover. We eliminate that fear by running old and new systems in parallel with automated reconciliation -- you switch over only when the new system has proven it produces the same results as the old one.
01
The Problem
Cutovers Based on Trust Instead of Proof
The problem is not one broken tool. It is an operating gap between who owns the work, which record can be trusted, and how exceptions move through the business.
What is actually happening
The workflow has no clean source of truth.
Records, rules, approvals, and handoffs are split across systems, so each step introduces delay or reconciliation.
What gets worse
Automation amplifies the weak spots.
The faster the business moves, the more bad data, exception work, and decision ambiguity compound across the operation.
02
What Changes
What Parallel Running includes.
The scariest moment in any migration is the cutover. We eliminate that fear by running old and new systems in parallel with automated reconciliation -- you switch over only when the new system has proven it produces the same results as the old one.
01
Dual Processing
Both systems process the same transactions simultaneously. Orders, invoices, inventory movements, and financial postings run through old and new in parallel.
02
Automated Reconciliation
Automated comparison of outputs -- order totals, inventory balances, financial summaries, and report data. Discrepancies flagged immediately for investigation.
03
Exception Reporting
Detailed reports on every discrepancy between old and new systems. Root cause analysis for each exception -- is it a bug, a data issue, or a business rule difference?
04
Cutover Criteria
Predefined, measurable criteria for when to cut over -- reconciliation accuracy threshold, exception count, and processing time. No subjective judgment calls.
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
Legacy system remains fully operational throughout parallel running. If the new system isn't ready, you continue on legacy with no disruption.

How It Fits Your Operations

Operations layerWhich manual workflow is costing the most time, rework, or decision delay.
Governance dependencyThe workflow needs clear ownership, trusted data, and exception rules before automation is worth building.

What Launchpad defines before engineering begins
- What the 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.

Decide what to build and in what order.
Launchpad assesses the business and turns discovery into priorities, risks, readiness, architecture, and an implementation Roadmap. Metrotechs then engineers and supports the approved solution.
Metrotechs designs, builds, integrates, and supports the approved solution.
Launchpad keeps priorities, risks, owners, decisions, and delivery governance connected.

Delivery sequence
How Metrotechs delivers Parallel Running.
The scariest moment in any migration is the cutover. We eliminate that fear by running old and new systems in parallel with automated reconciliation -- you switch over only when.
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 reconciliation meets the defined criteria, execute the cutover. Keep legacy in read-only mode for the defined safety period.

FAQ
Questions that usually decide the scope.
Straight answers to what operators ask before committing budget to this work.
Typically 2-4 weeks for transactional processes and one full month-end close cycle for financial processes. The duration depends on transaction volume and complexity -- you need enough data to be statistically confident.
