Reason. Evolve. Verify.
Ticomix REV™: Our AI-Assisted Legacy Conversion Methodology
Ticomix REV (Reason, Evolve, Verify) is our AI-assisted methodology for migrating legacy FoxPro, VB6, Delphi, and Access applications to modern .NET, cutting conversion timelines and cost while senior developers verify every step.
A Third Path for Legacy Conversions
Legacy conversions used to mean choosing between a slow, expensive manual rewrite and an automated converter that produces machine code nobody wants to maintain. REV is the third path: proprietary tooling and AI agents do the heavy lifting, and our developers make every decision that matters and verify every result.
Early Results
Based on our first AI-converted client project.
IN PRODUCTION
An aviation MRO shop’s FoxPro work-order and parts-tagging system (9 tables, 15 screens, 138,000 records) converted to a secure, multi-user .NET and Angular web app, including the regulated serviceable-part tags, reproduced exactly.
CURRENTLY UNDERWAY
A county cashiering system built in Visual FoxPro roughly 25 years ago (18 core tables, 31 screens, 9 reports, over 300,000 historical transaction records) being converted to .NET, Angular, and SQL Server. The first converted screens were deployed to a hosted test environment, running against fully migrated data, within the first week.
~40%
reduction in development time, roughly 66% faster than a conventional rewrite
First converted screens running against fully migrated data on a hosted test site within week one.
Lower Cost
Reduced architecture and rework overhead compared to a conventional rewrite.
Less Client Time
Fewer coordination and review cycles for your team during the project.
Faster
Days, not months, to the first working demo you can click through.
How REV Works
REV runs in three phases. Each one produces something you can see and evaluate before the next begins.
Reason
Reason is the discovery phase. Our AI agents document what your application actually does: the business rules, data structures, dependencies, and workflows. Discovery that used to take weeks of manual code archaeology now takes hours, and you get complete documentation of your system, including the rules nobody remembers writing.
Evolve
We rebuild your application as a modern .NET system, not a line-by-line translation. Evolve starts with your team defining what the new system should do beyond the old one. Our AI agents then execute the conversion plan while developers direct the architecture, delivering clean, maintainable code plus the capabilities your legacy platform never could: web access, integrations, and AI features.
Verify
Our developers verify the new system through code review, unit testing, and functional equivalence testing against the legacy system's documented behavior: everything the old application did, plus the new functionality defined during Evolve. AI accelerates the work; a developer signs off on every function, screen, and report before anything ships.
Where the Time Goes
The work shifts. It does not disappear. AI compresses discovery and development; developer time moves to directing the AI and verifying its output.
Why We Built REV
Automated tools give you speed without quality; manual rewrites give you quality without speed. REV exists because AI finally made both possible: automation for analysis and generation, developer judgment for design and verification. Ticomix has migrated desktop-era applications since the FoxBase era; REV is that experience encoded into a repeatable process and accelerated by tooling we built ourselves.
What Platforms Does REV Cover?
REV applies to the desktop-era platforms we specialize in:
- Visual FoxPro migration
- VB6 migration
- Delphi migration
- Microsoft Access modernization
The destination is modern .NET, deployed to the web, desktop, or cloud depending on how your team works.
These four are where we publish guides and have the deepest track record, but the methodology itself is platform agnostic. If your system runs on something else, like PowerBuilder, Clipper, or classic ASP, the same three phases apply. Talk to us.
Frequently Asked Questions About Ticomix REV
Automated converters translate legacy syntax into .NET syntax, producing code that compiles but mirrors the old system’s structure and is difficult to maintain. REV uses AI to understand your application’s business logic first, then rebuilds it as a modern system. You get current architecture and new capabilities, not a machine transliteration of 20-year-old code.
On our first completed REV project, development time dropped by roughly 40% compared to a conventional rewrite, making delivery about 66% faster. Once a project kicks off, the first converted screens are typically running against fully migrated data on a hosted test site within the first week. Smaller, well-structured applications take 8 to 16 weeks end to end; larger systems take 6 to 12 months.
AI generates significant portions of the analysis and code, and our developers direct, review, and refine all of it. Nothing ships without a developer verifying it against the original system’s behavior. The Verify phase exists precisely so you never have to take the AI’s word for anything.
The same way we test code a developer writes, plus one extra layer. Every component goes through developer code review and unit testing, and the converted system goes through functional equivalence testing: we verify it reproduces the legacy application’s documented behavior, using the system documentation built during the Reason phase. Nothing ships on the AI’s word alone.
Yes, and we plan for it. The Evolve phase begins by defining what the new system should do beyond the old one, from workflow improvements your team has wanted for years to capabilities the legacy platform could never support, like web access, integrations, and AI features. Scoping new functionality up front costs far less than bolting it on after the conversion.
Yes. Preserving your data is part of the Evolve phase: legacy data structures are migrated to a modern database, typically SQL Server, with integrity checks built into verification.
Complete documentation of your application’s business rules, data structures, and workflows. It is deliverable on its own, and some clients use it as an independent audit of their system before committing to a full conversion.
Any FoxPro, VB6, Delphi, or Access application that still runs your business. If your system is on a different legacy platform, talk to us; the methodology extends further than the four platforms we publish guides for.
