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.

Legacy System Modernization
Modernize the systems manufacturing still depends on. Legacy applications often contain undocumented product, order, inventory, production, pricing, and customer logic. We recover that knowledge, isolate dependencies, and modernize in controlled stages while preserving the operating capabilities that must continue.
01
The Problem
Critical manufacturing knowledge and workflows are trapped in systems that are difficult to support or change.
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.
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.
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 Legacy System Modernization includes.
Legacy applications often contain undocumented product, order, inventory, production, pricing, and customer logic. We recover that knowledge, isolate dependencies, and modernize in controlled stages while preserving the operating capabilities that must continue.
01
System Assessment & Documentation
Recover and document the business logic, data structures, integrations, dependencies, ownership, and operating scenarios required for a responsible modernization decision.

API Layer Development
Build a governed API layer over legacy systems so new manufacturing applications can use approved records without requiring core replacement first.
Related service03
Phased Migration Strategy
Replace modules incrementally -- move order management first, then inventory, then financials. Each phase is self-contained with rollback capability.
Related service04
Data Migration & Validation
Migrate required historical data through mapping, format conversion, cleansing, reconciliation, validation, exception reporting, and accountable acceptance.
Related service05
Parallel Running
Run selected old and new workflows together and reconcile the records and outcomes the business must preserve. Cutover follows approved operating thresholds, not superficial technical parity.
Related service06
Knowledge Transfer
Transfer the architecture, operations, support, recovery, and change knowledge required by the client's ownership model. The goal is a maintainable system, not a new undocumented dependency.

How It Fits Manufacturing
How Legacy System Modernization 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.

Start Your Transformation Roadmap
New material work begins in Launchpad so Metrotechs can validate the operating need, evidence, feasibility, architecture direction, and sequence before engineering begins.
Explore next stepStart With the Manufacturing 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 for the manufacturing operation.
A technical-service request does not bypass discovery. The proposed solution remains a working hypothesis until Metrotechs validates it in Launchpad.
04
Delivery sequence
How Metrotechs delivers Legacy System Modernization.
Legacy applications often contain undocumented product, order, inventory, production, pricing, and customer logic. We recover that knowledge, isolate dependencies, and modernize.
01
Discovery
Audit the legacy system -- business logic, data model, integrations, customizations, and tribal knowledge. Identify what must be preserved vs. what can be retired.
02
Strategy
Define the modernization path -- API wrapping, module-by-module replacement, or full platform migration. Present risk analysis and timeline for each option.
03
API / Integration Layer
Build the integration bridge between legacy and modern systems so governed records become available to operational analytics and automation.
04
Phased Replacement
Replace legacy modules one at a time with parallel running and validation gates. Each phase is a complete, tested unit before the next begins.
05
Decommission
Retire the approved legacy scope only after dependency closure, archival, access, retention, audit, recovery, and operating acceptance criteria are met.

FAQ
Questions that usually decide the scope.
Straight answers to what manufacturing leaders ask before committing budget to this work.
Yes. We can assess IBM i environments including RPG, COBOL, DB2 for i, interfaces, files, jobs, and terminal workflows, then determine whether documentation, supported integration, staged replacement, or migration is justified.
