Retire the system everyone is afraid to touch.
AI-accelerated code analysis and incremental migration that moves legacy logic to modern platforms without a big-bang cutover.
One call with a senior engineer. A straight answer on what it would take.
Where you are. Where you’ll be.
You need this if
- A core system runs on technology nobody hires for anymore
- Small changes to it take months
- A rewrite has been attempted and abandoned before
What changes for your business
- Budget moved from maintenance to new capability
- Business rules documented before the experts leave
- No high-risk cutover weekend
What we hand over
- AI-assisted code analysis and business-rule extraction
- Modernization roadmap with slice-by-slice sequencing
- Strangler-pattern migration with parallel-run verification
- Decommissioning of retired components
What it is
Legacy modernization replaces or rebuilds old business systems that are expensive to maintain and hard to change, often written in COBOL, early Java or .NET, or stored procedures. The hard part is usually knowledge, not code: few people still know everything the old system does.
Legacy maintenance can consume up to 80% of IT budgets, and the people who understand the code are retiring. Big-bang rewrites fail because nobody knows everything the old system does. We use AI to read and document legacy code (COBOL, old Java, .NET, stored procedures), extract business rules, then replace the system slice by slice behind a strangler pattern, verifying behavior at every step.
- Why now
- 90% of technology professionals now use AI at work, yet AI adoption still correlates with less stable delivery. DORA State of AI-assisted Software Development, 2025 (opens in a new tab)

How it runs
- 01
Diagnose
Typically 2–4 weeksWe map the problem, your data and your systems, and agree the one number that defines success.
- 02
Prove
Typically 4–8 weeksA working pilot on your real data, measured against that number. Not a slide demo.
- 03
Ship
Scoped to the outcomeProduction build with security, monitoring, cost controls and documentation included, not upsold.
- 04
Run
Ongoing, optionalWe operate what we built against clear service levels, or train your team to. Your call. No lock-in.
Questions you’ll ask
- What is the strangler pattern?
- A way to replace a system gradually: new components take over one function at a time while the old system keeps running the rest, until nothing is left of it. There's no single cutover weekend to go wrong.
- How does AI help with legacy code?
- AI tools can read large legacy codebases, explain what they do, document business rules and draft translations. Engineers verify every rule against real behavior, but the discovery that used to take months shrinks dramatically.
- Our previous rewrite was abandoned. Why would this one work?
- Rewrites usually fail because nobody knows everything the old system does. Extracting and testing the business rules first, then replacing in slices with side-by-side verification, removes the guesswork that sinks big-bang projects.
