Los Angeles, California - Legacy System Modernization

Legacy System Modernization for businesses in Los Angeles, California.

We reverse-engineer your legacy system\u2019s business logic, migrate your data, and replace aging platforms in governed phases -- so your operation never stops during the transition. Los Angeles produces more manufactured goods than any metro in the United States, but the narrative is dominated by entertainment and tech. Northrop Grumman's B-21 Raider program in Palmdale, SpaceX's Hawthorne rocket production, and Boeing's El Segundo satellite operations make the South Bay the densest aerospace corridor in the world. Below that defense-prime layer sits City of Industry — a municipality that is literally nothing but factories — where thousands of small and mid-market manufacturers produce everything from food packaging to precision machined parts under ITAR restrictions they barely understand.

Legacy System Modernization In Los Angeles

LA's manufacturing base is so fragmented across 12,000+ firms that no single initiative reaches critical mass — digital transformation here happens company by company, with almost no regional coordination or shared infrastructure.

What We Deliver In Los Angeles

Legacy System Modernization scope of work.

1

System Assessment & Documentation

Reverse-engineer and document your legacy system\u2019s business logic, data structures, integrations, and dependencies. Create the knowledge base that probably never existed.

2

API Layer Development

Build a modern API layer on top of legacy systems so new applications can integrate without touching the core. Unlock your data without the risk of a full replacement.

3

Phased Migration Strategy

Replace modules incrementally -- move order management first, then inventory, then financials. Each phase is self-contained with rollback capability.

4

Data Migration & Validation

Migrate decades of historical data with format conversion, cleansing, and validation. No data left behind, no data corrupted in transit.

5

Parallel Running

Run old and new systems in parallel with automated reconciliation. Switch over only when the new system proves it matches the old one\u2019s accuracy.

6

Knowledge Transfer

Train your team on the new systems and document everything. The goal is independence, not a new dependency on us.

How It Works

Our Legacy System Modernization process in Los Angeles.

1

Discovery

Audit the legacy system -- business logic, data model, integrations, customizations, and tribal knowledge. Identify what must be preserved vs. what can be retired.

2

Strategy

Define the modernization path -- API wrapping, module-by-module replacement, or full platform migration. Present risk analysis and timeline for each option.

3

API / Integration Layer

Build the integration bridge between legacy and modern systems. This alone often delivers immediate value by unlocking data for BI and automation.

4

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.

5

Decommission

Retire the legacy system with data archival, compliance documentation, and final validation. Clean cutover with no orphaned dependencies.

FAQ

Legacy System Modernization in Los Angeles FAQ

Can you work with AS/400 / IBM i systems?

Yes. We have extensive experience with AS/400 (IBM i) including RPG, COBOL, DB2/400, and green-screen applications. We can build API layers, extract data, and plan phased migrations off the platform.

What if nobody understands our legacy code?

That\u2019s common and expected. Our discovery phase reverse-engineers business logic from the running system -- examining data flows, testing scenarios, and interviewing users. We document what the system actually does, not what someone thinks it does.

How do you minimize risk during modernization?

Phased delivery, parallel running, automated reconciliation, and rollback plans at every stage. We never put your operation at risk with a big-bang cutover. If a phase isn\u2019t ready, we don\u2019t force it.

How long does legacy modernization take?

It depends on system complexity. An API layer can be built in 4-8 weeks. A full platform replacement typically takes 6-18 months with phased delivery. We deliver usable value at every phase, not just at the end.

AI, AWS, data, and operations In Los Angeles

AI Agents & Agentic Platforms

Most manufacturers are still running workflows that require a person to touch every exception, every order, every routing decision. AI agents eliminate that bottleneck — not by replacing your people, but by handling the work that was always below their pay grade.

AI, AWS, data, and operations

AI Demand Forecasting

Most manufacturers forecast demand with spreadsheets, gut feel, and last year's numbers adjusted by 5%. ML models trained on your actual order history, seasonality patterns, and market signals replace guesswork with predictions your planning team can act on.

AI, AWS, data, and operations

AI Predictive Maintenance

Odoo Maintenance captures work orders, failure reasons, repair times, and equipment history. We build AI models on top of that data to identify failure patterns and recommend maintenance windows before breakdowns occur — no new hardware, no IoT infrastructure required.

AI, AWS, data, and operations

AI Quality Analytics

Odoo Quality captures inspection results, non-conformances, scrap reasons, and lot traceability across every production order. We build AI models on top of that data to surface defect patterns, predict quality risk, and trigger alerts before scrap accumulates — no cameras, no hardware.

AI, AWS, data, and operations

AI Pricing Optimization

Most manufacturers price by cost-plus formula or by whatever the sales rep negotiated last time. AI pricing models factor in material costs, competitive positioning, customer segment, order size, inventory position, and market conditions — governed by business rules so every price stays within approved boundaries.

AI, AWS, data, and operations

Intelligent Order Routing

When an order hits your system, someone decides which warehouse ships it — usually based on habit, proximity, or whoever answered the phone. AI order routing makes that decision in real time, optimizing across inventory availability, shipping cost, delivery speed, and warehouse workload.

AI, AWS, data, and operations

AI Document Intelligence

Manufacturers still process thousands of POs, invoices, RFQs, spec sheets, and BOLs manually — reading PDFs, retyping data into the ERP, and fixing the errors that come with it. Document intelligence extracts structured data from unstructured documents automatically, with validation rules that catch errors before they enter your systems.

AI, AWS, data, and operations

Real-Time Inventory Visibility

Your dealers call or email to check stock before placing orders because they can't see what's available. We give them live ATP visibility across all your warehouses — available, allocated, in-transit, and expected replenishment dates — straight from your ERP and WMS.

AI, AWS, data, and operations

AWS Hosting & Infrastructure

We govern cloud migration in phases — every dependency mapped, every workload sequenced, every cutover window defined. Zero-downtime migration for manufacturers who can't afford an outage.

AI & Machine Learning

Most manufacturing AI projects die in the pilot phase. We deploy AI that integrates into your actual workflows -- demand forecasting, predictive maintenance, pricing optimization, and intelligent routing -- governed by operational data contracts.

Demand Forecasting Analytics

Your demand planning process runs on last year\u2019s sales adjusted by a gut-feel percentage. ML models trained on your actual order history, seasonal patterns, and market signals produce forecasts that are measurably more accurate \u2014 and they improve automatically as more data accumulates.

AI, AWS, data, and operations

API Layer Development

Your legacy system holds critical data that modern applications need -- but it has no APIs, no webhooks, and no modern integration points. We build a REST/GraphQL API layer on top of your legacy system so new applications can access data without touching the core.
