Legacy software modernization

Keep the business logic you trust. Build the software your business needs next.

We move Visual FoxPro, ColdFusion and other aging business applications to modern web software one workflow at a time, with your data checked at every step and every line of code yours.

Sound familiar?

The system still works. Everything around it is getting harder.

people

One developer knows it

Every change, fix and report request waits on one person’s calendar.

rules

Rules nobody wrote down

Pricing, approvals and exceptions live in the code and in people’s heads.

speed

Small changes take months

A new field or report turns into a project, so the business works around it.

reporting

Reports rebuilt in Excel

Data is exported, cleaned and re-keyed every week by hand.

access

Office-only access

Field staff and remote teams depend on remote desktop or wait until they’re back.

support

Uncertain support

Vendor updates have ended or are ending, and nobody can say what upkeep will cost.

Which platform runs your application?

How it works

Small, fixed steps. You decide after each one.

Nothing is rebuilt until the rules are understood, and nothing switches over until the new version matches the old one on your data.

  1. Free

    Readiness check

    Ten answers and an instant report on urgency, complexity and options.

    You get: a report and PDF to share internally

  2. Fixed scope

    Discovery

    We review the code, data and workflows with your team and recover the business rules.

    You get: a written plan, a first module and an estimate

  3. Fixed scope

    Pilot

    One valuable workflow rebuilt with your real data and acceptance tests agreed up front.

    You get: working software you can demo and keep

  4. Phased

    Modernization

    One workflow at a time, side by side, with reconciliation and a rollback plan for every cutover.

    You get: signed-off workflows and migrated data

  5. Optional

    Support

    Ongoing maintenance and improvements, or a clean handover to your own team.

    You get: code, docs and a trained team

Not every system needs a rebuild

Should you keep, upgrade, integrate or rebuild?

Keep it when it still does its job, someone can change it and backups are tested. Rebuild in phases when small changes take months, the rules are undocumented and the vendor no longer ships security updates. Most companies land in between.

OptionChoose it whenWatch out for
Keep and stabilizeIt works, changes are quick, and at least two people know the codeThe risk grows quietly as people leave
Upgrade in placeA supported release of the same platform exists, such as a newer ColdFusion or PHP versionNot possible for Visual FoxPro, VB6 or Classic ASP
Integration layerThe main pain is re-keying data or manual reportsIt eases symptoms but leaves the core unchanged
Phased rebuildChanges take months, rules live in people’s heads, and support has endedNeeds rule discovery and side-by-side testing, never a big-bang switch

Platforms we start with

Visual FoxPro and ColdFusion, answered plainly

.prg · .scx · .dbf · .cdx

Is Visual FoxPro still supported?

No. Visual FoxPro 9.0 was the final release, and Microsoft’s extended support ended in January 2015. Many VFP applications still run every day, so the end of support alone doesn’t mean yours must be replaced.

  • People: fewer developers know FoxPro each year.
  • Data: .dbf tables, often on a shared drive, with a 2 GB limit per table.
  • Access: desktop-only, so remote use needs remote desktop.
  • Windows: Microsoft lists versions up to Vista as supported for VFP 9.0.

Moving from FoxPro is a desktop-to-web move: new screens, a new database and a careful migration from .dbf tables.

Is ColdFusion still supported?

It depends on your release. Adobe still develops ColdFusion. ColdFusion 2021 reached the end of core support on November 10, 2025, and its extended support ends on November 10, 2026.

  • Extended support: Adobe says it is best-effort migration help and does not include security patches.
  • Upgrade path: Adobe points ColdFusion 2021 customers to ColdFusion 2025.
  • Rebuild: makes more sense when the code is hard to change or you want off the platform.

ColdFusion apps already run on the web, so upgrading in place is often a real option. We’ll tell you when it is.

What you can count on

How we protect the business while we change the software

You own everything

Code, documentation and data are yours from the first commit, whether or not you continue with us.

No blind code conversion

Rules are recovered from the code, written down and tested before anything is rebuilt.

Side by side, then switch

Old and new run together until totals and records match on your real data.

A rollback plan for every cutover

Backups, reconciliation and a way back are agreed before each switch.

Fixed scope before fixed price

Discovery and the pilot are scoped in writing. Changes go through an agreed change request.

Straight answers

If upgrading or keeping your system is the better call, we’ll say so.

FAQ

Questions buyers ask us

Can legacy code be converted automatically?

Automatic conversion rarely preserves business rules correctly. A safer approach recovers the rules from the code, writes tests for them, rebuilds one workflow at a time and runs old and new side by side until the results match.

Will we have downtime?

Each cutover is planned with backups, data reconciliation and a rollback path, and old and new systems run side by side first. No migration can promise zero risk, so we agree acceptance tests with you before each switch.

What happens to our data?

We profile it first, map every table to the new schema, migrate it in rehearsals, and reconcile counts and totals before go-live. Your current system keeps running until each workflow is signed off.

Who owns the new code?

You do. Code, documentation and data stay yours, whether or not you continue with us after a pilot.

What technology do you build with?

We choose after discovery. Web interfaces are often built with Next.js, and APIs and integrations with Python and FastAPI on PostgreSQL. The right choice depends on your team, hosting and workflows.

Is Visual FoxPro still supported?

No. Visual FoxPro 9.0 was the final release, and Microsoft’s extended support ended in January 2015. Many VFP applications still run every day, so the end of support alone doesn’t mean yours must be replaced.

Is ColdFusion 2021 still supported?

ColdFusion 2021 reached the end of core support on November 10, 2025, and its extended support ends on November 10, 2026. Adobe describes extended support as best-effort migration help without security patches, and points customers to ColdFusion 2025.

Is the readiness report a technical audit?

No. It’s based only on your answers. Discovery reviews the code, data and workflows to confirm or correct it.

Do you work with software agencies?

Yes. Agencies can bring us in as a white-label delivery partner for their clients’ legacy systems.
