Modernization engineering for real businesses

Fade out the legacy.Fade in what comes next.

Legacy Fade rebuilds the software your company depends on, one safe step at a time. Desktop and web apps, APIs, databases, pipelines and Active Directory, moved onto a modern stack while the business keeps running on top of it.

The problem

Your oldest software is still making money.

It also runs on a framework that stopped getting updates, builds on one machine, deploys by copy and paste, and is understood by fewer people every year. Rewriting it all at once is how projects fail.

Legacy Fade takes the other route. We wrap the system you have, make it safe to change, and replace it piece by piece until the old stack can simply be switched off. Your users keep working the whole time.

What we fade

Every layer of the stack, modernized.

From a single stubborn desktop app to the pipelines, identity and data underneath an entire portfolio.

Drag the handle

Same data. Different decade.

Modernization is not a coat of paint. Behind the new screen sit typed APIs, automated deployments, structured logs and sign-in that your directory controls.

  • Business rules moved out of the UI and into tested services
  • The same database, with access through clean data layers
  • Works on any device, signs in with your existing accounts
  • Shipped by pipeline, monitored in production
The fade

Five phases. No cliff edge.

Each phase leaves you better off than the one before, even if you stop there.

  1. 01

    Discover

    Inventory the applications, data, integrations and the people who depend on them. Map dependencies and rank risk so the plan starts where it pays off first.

  2. 02

    Stabilize

    Source control, repeatable builds, structured logging and tests. Make the legacy system safe to change before changing it.

  3. 03

    Bridge

    Put APIs and integration seams around the old system so new pieces can run beside it. Old and new share the load while trust is earned.

  4. 04

    Rebuild

    Replace capabilities one slice at a time on a modern stack, shipped through automated pipelines, measured with real usage.

  5. 05

    Retire

    Switch off what is no longer needed, archive what must be kept and hand over documentation your team can own.

Track record

Built, migrated and running in production.

Modernization

Fleet-wide desktop platform migration

End-of-life framework risk removed across the portfolio, faster builds and a clean path to future framework upgrades.

  • WinForms
  • VB.NET
  • C#
  • .NET 8 / 10
DevOps

Shared pipeline template library

A force multiplier: every team that consumes the templates inherits the same signing, deployment and audit behavior.

  • Azure DevOps
  • YAML
  • PowerShell
  • MSBuild
Data

Schema snapshots and environment drift reporting

Close to a thousand false flags reduced to a few dozen genuine differences, so the report is trusted and acted on.

  • SQL Server
  • Database Projects
  • Azure DevOps
  • C#
01

No big-bang rewrites

Incremental replacement keeps revenue flowing and lets each step prove itself before the next one starts.

02

Root cause over patches

When something breaks we find out why, and fix it where it starts so the same problem does not come back elsewhere.

03

Production is sacred

Changes are scripted, reviewed and reversible. Database changes come with preview queries, transactions and a backup plan.

04

You own the result

Clean code, documentation and pipelines your team can run without us. No lock-in, no mystery boxes.
