Legacy System Conversion

Cut years of technical debt in months, not quarters.

We deploy teams of elite AI agents running systematic agentic workflows — not vibe coders guessing their way through your codebase. Every conversion step is structured, tested, and traceable.

The Process

Legacy code goes in. Modern architecture comes out.

Triptych reads your legacy codebase the way a fax machine reads a page — capturing every business rule, workflow, and intent buried in decades of code. Our specialized agentic teams use that deep understanding to rebuild the system in a modern language with modern UI/UX, preserving the logic that matters while leaving the baggage behind.

Deep Business Logic Capture

Triptych maps every business rule, workflow, and hidden intent in your legacy code — so nothing critical gets lost in translation.

Modern Language, Modern UX

Your system is rebuilt in a current stack with a clean UI/UX — not a 1:1 port, but a genuine upgrade that your team and users will actually prefer.

Engineers + AI, Not AI Alone

Senior engineers drive every decision, using AI as a force multiplier. Structured workflows keep quality high — no vibe coding, no guesswork.

Production-Ready Infrastructure

The new system ships on cloud-native, containerized infrastructure with CI/CD built in — ready for your team to operate and scale from day one.

The Results

Speed you can measure. Progress you can see every week.

Traditional rewrites take years and often fail. Our agentic approach compresses timelines and delivers working milestones from the first sprint.

VS. TRADITIONAL DEVELOPER

2–3K lines/month

1,500x

A single developer writes 2–3,000 lines of production code per month. Our agentic teams produce 4–5 million — the equivalent output of an entire engineering department.

VS. VIBE CODING

20–30K lines/month

150x

Vibe coders using ChatGPT and Copilot hit 20–30K lines per month — but with bloated context windows that inject bugs, misalign intent, and produce brittle refactors. Triptych gives each agent a carefully curated context window scoped to exactly what it needs, so 4–5 million lines ship clean.

QUALITY AT SCALE

CMM-5 workflows

Self-healing

Speed means nothing without quality. Our agentic workflows operate at CMM-5 maturity — continuously self-diagnosing, self-correcting, and improving with every sprint. No regressions. No drift.

Why This Works

Sounds too good to be true? Here's why it isn't.

01

"Isn't this just AI hype?"

Triptych isn't a chatbot wrapper. It's a proprietary code intelligence engine that builds a semantic map of your entire codebase — every business rule, every dependency, every side effect — before a single line is rewritten. Each agent operates within a curated context window scoped to exactly the work it's doing. The methodology is structured, auditable, and repeatable.

02

"How do you maintain quality at that speed?"

Every pull request passes through automated review gates, test harnesses validated against real production behavior, and human oversight at every stage. The workflow self-diagnoses regressions and corrects before they reach your branch. It's CMM-5 maturity built into the pipeline — not a process document on a shelf.

03

"What if it doesn't work for my codebase?"

That's what the feasibility review is for. Before you commit a dollar, we run Triptych against your codebase and give you a clear scope: what can be converted, what the timeline looks like, and where the real risk lives. If it's not a fit, we'll tell you — and you'll still walk away with the deepest analysis of your legacy system you've ever seen.

Before You Call

The questions every CTO asks. Answered honestly.

If your question isn't here, the feasibility review will cover it — with specifics for your codebase, not generics.

01

What happens to my team during the conversion?

They keep shipping. Our agentic teams work in parallel on the conversion while your developers stay focused on the current roadmap. When modules are ready, we hand them over with full documentation, test suites, and a walkthrough — so your team owns the new code from day one, not day 180.

02

How long does a typical legacy conversion take?

Most engagements deliver the first working milestone in Week 1 and complete a bounded conversion phase in 8–12 weeks. The feasibility review will give you a precise scope and timeline before you commit. We don't do open-ended rewrites — every sprint has a defined deliverable.

03

What if our legacy system is undocumented spaghetti code?

That's actually our sweet spot. Triptych was built for exactly this — it reads the code as-is, maps every business rule and dependency regardless of documentation, and produces a semantic model of what the system actually does. The worse your docs, the more valuable the analysis.

04

What languages and frameworks can you convert from and to?

We've converted from COBOL, VB6, Classic ASP, legacy Java, PHP 5, and Delphi into modern stacks like .NET 8, React/Next.js, Python, and Go. Triptych is language-agnostic at the analysis layer — it understands intent, not just syntax.

05

What does the feasibility review cost?

The feasibility review is a paid engagement — typically 1–2 weeks — but it's the most valuable first step you can take. You get a complete Triptych analysis of your codebase, a scoped conversion plan, a realistic timeline, and a clear risk assessment. If we're not a fit, you keep the analysis. No one else will give you that level of insight into your own system.

Final Step

See if this scope is worth compressing into one sprint.

A short review call is enough to determine whether the work is a fit, what should stay out of scope, and where delivery risk actually sits.
