From Uniface 4GL to a modern, testable codebase

A simplified example of how business logic and UI are redeveloped. Actual conversion preserves your application’s full logic, verified module by module against the original.

Uniface 4GL (illustrative)

trigger validate
  if (Qty <= 0)
    message "Qty must be > 0"
    return
  endif

  Total = Qty * Price

  if (Total > CreditLimit)
    message "Exceeds credit limit"
    return
  endif
end

.NET C# (business logic)
public class OrderValidator
{
  public Result Validate(Order o)
  {
    if (o.Qty <= 0)
      return Fail("Qty must be > 0");

    o.Total = o.Qty * o.Price;

    if (o.Total > o.CreditLimit)
      return Fail("Exceeds credit limit");

    return Success();
  }
}
React (UI layer)
function OrderForm({ order }) {
  const err = validate(order);

  return (
    <Form>
      <QtyInput value={order.qty} />
      {err && <Error text={err} />}
      <Submit disabled={!!err} />
    Form>
  );
}

Simplified for illustration only, not a literal excerpt of any client’s codebase.

The challenge

Why Uniface applications need to move, and why now

Hover each card to read the full picture.

The problem

Your Uniface application works.
But it’s costing you.

Uniface specialists are harder to find, licensing and specialist costs keep rising, and modern integrations take extra effort.

The problem

Your Uniface application works. But it’s costing you.

Uniface isn’t ageing technology. It’s still actively supported and evolving, and applications built on it continue to run reliably. The real cost sits around it: Uniface specialists are harder to find and more expensive to hire every year, licensing costs add up over time, and integrating with modern tools and services takes more effort than it does on mainstream stacks, even though that integration is entirely achievable. The longer the move waits, the more those costs compound.

The solution

TFT removes the
uncertainty.

In-house Uniface engineers plus AI-assisted conversion, reviewed by engineers every time.

The solution

TFT removes the uncertainty.

Modernising Uniface isn’t a simple migration. It takes engineers who understand what the application actually does, not just what the code says. TFT pairs in-house Uniface engineers, who extract and document your business logic, with a modern-stack team who rebuild it right, using AI-assisted tooling to accelerate analysis and code conversion, with every module reviewed by engineers before it ships.

What We Build

What backs TFT’s Uniface capability

Rather than lead with numbers we can’t yet verify, here’s what you can actually check.

Dedicated in-house team

The engineers who read your codebase stay on the engagement from Discovery through Deployment & Hypercare, not subcontracted specialists rotated in for one phase.

Enterprise-grade certifications

ISO 27001, ISO 9001, and CMMI Level 3 apply to every engagement TFT runs, Uniface redevelopments included, not just the wider portfolio.

Backed by a full delivery organisation

Uniface work draws on TFT’s broader engineering organisation, with delivery centres across the US, Germany, UAE, Mexico, Israel, and India, not a standalone boutique practice.

A documented, transparent process

Every phase from Discovery to Deployment & Hypercare has named deliverables, shown earlier on this page, so you know exactly what you’re getting before you commit.

Our Approach

Quality-Driven Development Process

A structured methodology that supports fast-moving projects, evolving requirements, and long-term scalability.

Discovery

We agree on project scope, objectives, and deliverables together. For larger or higher-risk applications, we can also scope a Proof of Concept on a representative module first, to validate the approach before committing further. This creates a clear and collaborative approach to the redevelopment from day one.

Analysis & Planning

We review the Uniface export, map all dependencies, identify redevelopment risks, and prepare a customized pricing proposal before any conversion begins. You receive a clear picture of scope, stack recommendation, effort, and cost before committing further.

Code Migration

Your Uniface business logic is rebuilt on your chosen modern stack, module by module. We provide the converted codebase and a report covering all redevelopment points, including any out-of-scope components flagged for client action. Timeline is set during Analysis & Planning based on your application’s scope.

Testing

You validate the migrated application in your own environment. We resolve issues identified during testing and confirm deployment readiness before sign-off. Duration aligns to your project and environment.

Deployment & Hypercare

We support production deployment using best-practice guidance, then remain engaged through a Hypercare period (typically 3–6 months) resolving any issues at no additional cost. Beyond Hypercare, ongoing application maintenance and support plans are available to keep the application stable, performant, and evolving. Your team also receives full documentation and knowledge transfer to operate independently.

Engagement models

Four ways to start, sized to your risk appetite

You do not have to commit to a full redevelopment to get a defensible answer. Each model below is a separate, scoped decision point, and most engagements begin with the first one.

Uniface Migration Analysis

Fixed scope, quoted upfront

You send a Uniface export. TFT's Uniface engineers read the codebase, map dependencies and business rules, and return a redevelopment plan with a stack recommendation. Typically about a week.

Codebase scan report

Stack recommendation with rationale

Customized pricing proposal

No obligation to continue

Proof of Concept

One representative module

For larger or higher-risk applications, one module is redeveloped end to end first. You see real working software on the proposed stack before the full budget is committed.

One module on the new stack

Functional equivalence demonstrated

Validated effort model for the rest

Go / no-go decision on evidence

Full Redevelopment

Phased, module by module

The complete application is rebuilt on your chosen stack in delivery cycles, each one tested against the live Uniface system. No big-bang cutover, and working software long before the final module.

Module-by-module delivery

Functional equivalence testing

Parallel running during transition

Hypercare after go-live

Build-With Embedded Team

Your developers, on the inside

TFT engineers work inside your team rather than beside it. Your developers commit to the new codebase from the first module, so ownership is built during the project instead of handed over at the end.

Shared repository and standards

Your team reviews and commits

No documentation-only handover

Independence at go-live, not after

Make the Right Choice

Four routes out of a legacy Uniface application, side by side

Redevelopment is not the only option, and it is not always the right one. Here is an honest comparison of the four routes most organisations evaluate, so the trade-offs are visible before you choose.

Consideration	Stay on Uniface (version upgrade)	Re-platform to a low-code product	TFT phased redevelopment
Business logic	Fully preserved, because nothing is rebuilt.	Largely carried over, but reshaped to fit the new platform's model.	Read, documented, and rebuilt against an explicit map, then verified for functional equivalence.
Front end	Still a Uniface interface, with the same constraints.	Modern, within the boundaries of what the platform's UI layer allows.	React or Angular, with no ceiling on what the interface can do.
Talent pool afterwards	Unchanged. You continue competing for a shrinking pool of Uniface developers.	Platform-specific skills, more available than Uniface but narrower than mainstream.	Mainstream .NET, Java, Python, React, and Angular engineers, hireable in any market.
Platform dependency	Continues, including licensing and roadmap.	Removed.	Removed. The output is a standard codebase on standard frameworks that you own outright.
Integration with modern APIs and cloud	Possible but effortful, and constrained by the 4GL runtime.	Good, through the platform's connectors.	Native, because the result is an ordinary modern application with ordinary integration options.
Where the risk sits	Deferred rather than removed. The same decision returns at the next upgrade.	Fit risk: how closely your logic maps to the platform's model.	Distributed across modules. Each one is tested against the live Uniface system before the next begins.
Time to first working software	Immediate, but nothing has changed.	After platform configuration and initial model import.	After the first delivery cycle, then continuously.
Cost profile	Recurring: licences, upgrades, and scarce specialist maintenance.	Project cost plus ongoing platform subscription.	Fixed-scope analysis first, then a proposal priced against your actual codebase.

Complete Guide

What you gain

10 outcomes of choosing TFT for Uniface migration

01 / 10

Choice of target stack

You choose the technology your application runs on: .NET, Java, or Python on the back end, React or Angular on the front end. TFT makes a recommendation based on your architecture and team, but the final decision is always yours.

02 / 10

Business logic preserved

TFT engineers read and document every business rule, workflow, and data logic before redevelopment begins. Each module is built against this map and verified for functional equivalence before it ships. Nothing your organisation depends on is lost.

03 / 10

AI-compressed timeline

TFT’s AI-assisted tooling analyses your Uniface codebase, maps dependencies, and generates conversion artefacts, improving accuracy, reducing manual engineering effort, and compressing the analysis and conversion phases from months to weeks. Every output is reviewed by engineers before use.

04 / 10

Reduced redevelopment risk

With 50+ man-years of Uniface experience, TFT has seen the patterns before. Scoping estimates are accurate. Risk areas are identified early. Complexity that surprises a first-time partner is expected and planned for.

05 / 10

Functional equivalence guaranteed

Every module is tested against the legacy Uniface system before it is accepted. TFT runs both systems in parallel, compares outputs, and resolves every discrepancy before UAT begins. Nothing moves to production without equivalence sign-off.

06 / 10

Phased delivery

Redevelopment happens module by module. You receive working software at the end of every phase, risk is distributed, and there is a review point before each new cycle. You can run completed modules in production before the full application is done.

07 / 10

Build-with model

Your internal team can work alongside TFT engineers during the build, not waiting for a handover document at the end. Knowledge is transferred through doing. TFT’s structure enables this from the start of the project.

08 / 10

Mainstream platform

Your application moves onto .NET, Java, or Python: mainstream stacks with deep talent pools and large ecosystems. Hiring and infrastructure options open up immediately after go-live.

09 / 10

Wider talent pool

Recruiting for .NET, Java, Python, React, and Angular is a standard hiring exercise globally. You stop competing for a shrinking pool of Uniface specialists and open every role to the mainstream developer market.

10 / 10

Full documentation handover

Every project concludes with a complete documentation package: architecture documentation, code documentation, a record of the migration approach and key decisions, deployment and operational guides, and knowledge transfer documentation. Your team can operate, extend, and evolve the application without depending on TFT after go-live.

FAQ

Uniface migration & modernization: your questions answered

How long does a Uniface migration take?

Timeline depends on your application’s size and complexity, so we don’t quote an overall duration upfront. What we do commit to is the Analysis & Planning phase, which typically takes about a week and gives you a precise, scoped timeline and cost for the rest of the engagement before you commit further. Because TFT delivers module by module, working software on your chosen stack is available earlier than a big-bang cutover would allow.

How is the engagement priced?

Every engagement is scoped individually. The Analysis & Planning phase is quoted upfront, so you have a clear, defined cost before deciding on anything further. Once that phase is complete, you receive a customized pricing proposal for Code Migration and Deployment based on your application’s actual scope. Contact us and we’ll put one together for your specific project.

What happens to existing Uniface business logic?

TFT’s in-house Uniface engineers read and document the existing business logic as the first step of every engagement. Business rules, workflows, and data logic are mapped explicitly before redevelopment begins. Each module is built against this map. The functional equivalence testing phase then verifies that the new application reproduces the behaviour of the original, including rules that were never formally documented.

Which technology stack does TFT recommend?

TFT does not have a default recommendation. Stack selection is based on analysis of your Uniface application, your team’s existing skills, your infrastructure environment, and your long-term roadmap. Back-end options are .NET, Java, or Python. Front-end options are React or Angular. The formal recommendation is a deliverable from the Analysis and Planning phase. The final decision is always yours.

How does TFT handle testing after redevelopment?

In the Testing phase, you validate each redeveloped module in your own environment, running it against the existing Uniface system to confirm functional equivalence. TFT resolves discrepancies and issues identified during testing. No module moves to the next development cycle without a sign-off. The Deployment & Hypercare phase then supports production deployment across all completed modules.

What support do we get after go-live?

Every deployment includes a Hypercare period (typically 3 to 6 months) during which TFT resolves any issues that surface in production at no additional cost. Beyond Hypercare, ongoing application maintenance and support plans are available, so you have a long-term partner for stability, performance, and continued evolution of the application, not just a one-time handover.

Can we start with something smaller than a full migration?

Yes. For larger or higher-risk applications, TFT recommends starting with a Proof of Concept on a representative module. This validates the redevelopment approach and stack recommendation and lets you assess feasibility before committing to the full-scale engagement.
