AI Legacy Modernization
Modernize your legacy without stopping the business
with the operation never going down
system in eight weeks
before a single line of code moves
The problem
Where legacy sends the bill
The old system isn't only a technical matter. It sets what every new release costs, how much time the team loses, and the risk the operation carries every day.
Nobody knows what the system does
The business rules live in the code and whoever wrote them has left. Touching it is risky, and documenting it from scratch feels impossible.
Technical debt is throttling delivery
Every new feature costs more than the last. The team spends more time working around the system than building on it.
Stopping the operation isn't an option
The system runs the business. There's no window to shut it down and migrate, so modernization has to happen with everything live.
Maintenance costs keep climbing
Licenses for aging technology, on-premise infrastructure, and the handful of people who still know how to keep it alive. The bill rises every year.
How we think
Rewriting everything is the most expensive and riskiest path
A full rewrite erases years of business rules nobody documented, and only pays out at the very end — if it gets there. We'd rather map what the system actually does first, choose the strategy per component, and migrate in phases with the new running alongside the old. Every phase delivers value on its own.
What we modernize
From discontinued languages to legacy databases, discovery starts by understanding the current stack before proposing any path.
Legacy Languages
AI-assisted code analysis and migration from COBOL, Visual Basic, Delphi, or discontinued frameworks to stacks that are still supported.
Monolith to Microservices
AI-powered dependency mapping and decomposition of the monolith into independent services, via the strangler fig pattern — no big-bang cutover.
Cloud Migration
Moving off your own datacenter to AWS, Azure, or Google Cloud, with the strategy chosen per component.
Database Modernization
Upgrading legacy databases, with the rules that live in procedures and triggers mapped first.
Our modernization approach
Incremental modernization that keeps the business running, from mapping the critical rules to safely decommissioning the old system.
01
Legacy discovery
We map critical business rules, integrations, and risks, with AI-generated system specs. Eight weeks, ending in the migration plan.
02
Strategy per component
Not everything migrates the same way. Each part gets the right approach — rehost, replatform, refactor, or rebuild — by risk and return.
03
Phased migration
The new system grows alongside the old one and takes over function by function. The operation never stops, and returns land before the end.
04
Safe decommissioning
The legacy system only goes dark once every function has a validated equivalent in production, with a rollback plan at each step.
Strategies
Modernization strategies
The choice is made per component, not for the whole system. Each part gets the approach that makes sense for its risk and its return.
Why Luby
Modernize without erasing what works
Legacy holds years of business rules nobody documented. Recovering that knowledge before moving code is what separates a migration from a blind rewrite.
AI-generated specifications
We recover the documentation that doesn't exist by reading the code itself. That's what makes mapping a system nobody understands viable.
The operation never stops
Incremental migration with the new running alongside the old. No downtime window, no risky big-bang cutover.
Returns before the finish line
Every phase delivers value on its own. You don't wait two years to see the first benefit of modernizing.
Strategy per component
Rewriting everything is the most expensive and riskiest path. Rehost, replatform, refactor, and rebuild are chosen part by part.
Benefits
What modernizing buys you
Improved Performance
Faster response times and a better user experience on a modern architecture.
Reduced Costs
Lower maintenance and infrastructure spend on cloud-native foundations.
Enhanced Security
Modern security practices and compliance with current standards.
Better Scalability
Scale resources up or down as demand moves.
Faster Time to Market
Ship new features faster on modern development practices.
Future-Proof Technology
Built on supported, actively developed technology stacks.
The metrics we chase
The number the modernization answers to
Modernizing isn't an end in itself. The metric is agreed at the start and measured throughout the migration, phase by phase.
Maintenance cost
Time to ship a new feature
Availability during migration
Coverage of mapped business rules
Deployment frequency
