Legacy / Product Modernization

The last rewrite stalled.This one starts with a map, not a phase.

We start with a paid feasibility review — a complete map of what your system actually does — before you commit to a conversion phase. Because lift-and-shift moves the debt to the cloud. Incremental refactoring preserves the old architecture. Big-bang rewrites die because the only spec is the old code.

The feasibility review is a paid engagement, typically 1–2 weeks. Tell us the system and what it is costing you. You will hear within 24 hours whether it is a fit. If it is, the review scopes the conversion before you commit to a phase.

  • The feasibility review produces a dependency map, scoped conversion plan, realistic timeline, and risk assessment. You keep all four whether or not you proceed.
  • The first working milestone arrives in week one of the conversion phase. Bounded, fixed-fee, scoped before work starts.
  • The conversion runs alongside your existing system. Both stacks stay live. Your team keeps shipping their roadmap.

Why rewrites fail

Every escape route from a legacy system has a known failure mode.

  1. Lift-and-shift moves the debt to the cloud — same architecture, same coupling, now with a cloud bill. Incremental refactoring preserves the old architecture by definition; after two years you have modernized spaghetti.

  2. Big-bang rewrites die because the only spec of the system is the old code and the memories of departed engineers. AI code translation is the newest trap: it faithfully reproduces every bad decision in a new syntax.

  3. The behavior is the asset. The code is the liability. Separating them is what the feasibility review is for — and it happens before you commit to a phase.

The path

A map first. Then a bounded phase. Then the next one.

  1. Paid feasibility review — typically 1–2 weeks

    Triptych reads the existing codebase as it stands today and maps every business rule, dependency, and control flow directly from the code — no documentation required. Output: complete dependency map, scoped conversion plan, realistic timeline, and written risk assessment. Yours to keep regardless of next steps.

  2. Bounded conversion phase — 8–12 weeks

    Scope written before work starts. First working milestone in week one. Both stacks run in parallel. Weekly working demos, not status decks.

  3. Phased modernization

    Each phase has a defined deliverable and written success criteria. Technical debt does not migrate forward — only what the system does is rebuilt, in modern infrastructure.

  4. Ongoing or handoff — your choice from day one

    Code, infrastructure, documentation, and deployment pipelines transfer at handover. No lock-in, no proprietary dependencies.

What you receive

Every stage produces something you keep.

  • Dependency map, scoped conversion plan, realistic timeline, and written risk assessment — yours to keep.

A healthcare SaaS company’s UI modernization had been stalled for 18 months. Reframed, scoped, and shipped in 6 weeks — without pulling the internal team off their roadmap.

The commitment

Initial conversion phase: typically $15K–$50K+, fixed after the feasibility review.

That number is not set from a sales conversation — it is set from an analysis of what the actual codebase contains and what the phase requires.

Written scope, assumptions, exclusions, and success criteria are agreed before any phase begins. If the conditions that make the engagement viable are not present, we say so before work starts — not after a phase is underway.

Done before, under load

The constraint modernization has to respect: the system cannot go down.

01 / 03

01

KeyCentrix — COBOL to .NET, live throughout

At KeyCentrix — a pharmacy software company Brandon Shuey built and ran — the core dispensing platform ran on COBOL. It was redesigned to .NET: thirty developers, two years, the legacy system live for hundreds of independent pharmacies through the entire cutover. No service interruption to the businesses depending on it.

02

Contract management SaaS — four weeks

Legacy CLM data extraction was blocking a SaaS product roadmap. Removed in 4 weeks. 50,000+ records extracted. The core product team was unblocked.

03

The pattern is structural, not vertical

The same bounded-first pattern — feasibility review, parallel-stack conversion, phased delivery — holds across logistics, healthcare, pharmacy, legal tech, and enterprise SaaS.

Who makes the calls

30+ years shipping production systems. Five times founder, CEO, CTO, or architect — the failure modes of modernization are already familiar to the person making the calls.

That is the constraint modernization has to respect: the system cannot go down, and the business cannot pause to migrate.

Before you call

The objections, answered once.

If yours is not here, it is a two-minute email and a direct answer within a day.

  • The feasibility review sets scope from an analysis of the actual codebase before a dollar is committed to a phase.

Take it when

A business-critical system is holding the company back — change is slow, the stack is unsupported, key people are leaving, or diligence flagged it — and you want the scope mapped before committing to a phase.

Pass when

An open-ended rewrite program with no bounded first phase, or a modernization with no economic owner inside the business.

What happens next

  1. 01

    Tell us the problem — two minutes.

  2. 02

    Direct answer within 24 hours on whether it’s a fit.

  3. 03

    If it is: a 30-minute scoping call.

  4. 04

    Written scope, timeline, and fixed fee before any work starts. You keep everything delivered.

Results depend on the specific system, its complexity, and the scope agreed before work starts.

Final step

The system is not getting easier to own.

Tell us the system and what it is costing you — 2 minutes. Direct answer within 24 hours: fit or not. If it is a fit, a 30-minute scoping call, then written scope, timeline, and a fixed fee for the feasibility review. The phase price follows the analysis, not the conversation.

No pitch. No prep. If it is not a fit, I will tell you.
