Software Development — Windows & Linux Replatforming
Windows & Linux Replatforming
Legacy Windows and Linux applications moved onto modern, supportable infrastructure — same business logic, without the end-of-life risk of the platform underneath it.
What replatforming covers
Moving Legacy Applications Off Infrastructure That’s Running Out of Runway
Not a rewrite. The application logic your business depends on comes forward — the platform underneath it changes.
Why replatform instead of replace
The Application Usually Isn’t the Problem — the Platform Underneath It Is
Most legacy Windows and Linux applications we’re brought in on aren’t broken. They do what the business needs. What’s failed is the platform underneath them — an OS past end of support, a framework version nobody patches anymore, hardware nobody wants to be responsible for when it finally dies.
Replacing the application outright means re-specifying and re-testing business logic that already works, on a timeline usually measured in years. Replatforming moves the same application forward — onto a supported OS, a current runtime, infrastructure your team can actually maintain — without touching the logic that already works.
We start by mapping what the application actually depends on: integrations, scheduled jobs, file shares, other systems that talk to it. Migrations fail more often from an undocumented dependency than from the migration itself.
Common Requests
- An application running on a Windows Server version past end of support
- Legacy .NET Framework code that needs to move to a current runtime
- A Linux application tied to hardware nobody wants to maintain
- Moving a physical server workload to virtualized or cloud infrastructure
- A database platform reaching end of support alongside the application

Where This Fits With What Else We Do
If the legacy platform in question is IBM i rather than Windows or Linux, that’s a different kind of work with its own approach — see IBM i modernization. If the application needs a browser-based interface as part of the move, see web development.
FAQ
Windows & Linux Replatforming Questions
Do you rewrite the application, or move it as-is?
We move it, adapted for the new platform — not a rewrite from a blank spec. The business logic your application already enforces comes forward with it.
What if we don’t have documentation for the application?
That’s the normal starting point. We map dependencies and integrations by tracing the running system rather than relying on documentation that may not exist or may be out of date.
Can you migrate the database along with the application?
Yes — when the database platform is also reaching end of support, we plan and execute that migration as part of the same engagement.
Do you handle cloud migration, or only on-premises replatforming?
Both. Where cloud or virtualized infrastructure is the right destination, we plan and execute the move there rather than just replacing one physical server with another.
