to your stack & domain

Move a defined .NET Framework application toward a supported modern .NET runtime and deployment model, in staged, low-risk increments.

How this operator works

every way of working, already decided

A · capability focus

Owns the system, not the ticket

Takes end-to-end ownership of a service or surface. Design, delivery, on-call. And is measured on outcomes, not hours.

B · ways of working

Embedded, async-first, instrumented

Works inside your repos, your CI and your rituals. Daily written standups, decisions logged. No status-meeting tax.

C · reliability posture

Runbooks, canaries, reversible deploys

Every change gated and reversible. Incidents get a timeline and a postmortem; nothing ships without a rollback.

D · comms & cadence

Plugged into your Slack & rituals

Joins standups and retros, reports weekly against the goal. You get an operator, not a queue.

E · tooling

Brings a pre-wired stack or adopts yours

Infrastructure and observability as code by default. No bespoke setup tax to absorb.

F · onboarding

Scoped, gated, reversible

Week-1 shadow, week-2 ownership, swap on request inside the trial window. No long-tail handover risk.

Overview

Applications stuck on .NET Framework carry compounding cost: Windows-only hosting, aging dependencies, and a shrinking hiring pool. This package moves a defined .NET Framework application toward supported modern .NET, current runtime, updated dependencies, and a modern deployment model, without betting the business on a big-bang rewrite. The finish state is the application running on a supported runtime with a repeatable path for whatever scope remains.

The approach de-risks the rewrite: portability analysis first, then staged migration, upgrading projects incrementally, replacing framework-only dependencies, and applying strangler-fig patterns where components need rebuilding rather than porting. AI-assisted migration tooling accelerates the mechanical work; engineering judgement handles the rest. Deployment lands on containers or cloud services as fits your estate.

What's included

Portability assessment

The codebase analysed for migration blockers, framework-only dependencies, and effort by component.

Staged migration

Projects upgraded incrementally to modern .NET, with the application kept releasable throughout.

Dependency and API remediation

Unsupported packages and APIs replaced with maintained equivalents.

Modern deployment model

The migrated application deployed via containers or cloud services, with CI/CD wired in.

How it works

Scope: run the portability assessment, agree the migration order and acceptance criteria.
Build: migrate in stages, remediating dependencies and keeping the application shippable at every step.
Handover: cut over to the modern runtime and deployment, hand over documentation and the residual map.

Part of every Delivery Plan

The Legacy .NET Modernization is a menu item on the Scrums.com delivery catalog, available at every plan tier. Add it to your plan backlog and your delivery team schedules it like any other item — scoped, tracked, and reported through the SEOP. See Delivery Plan Tiers.

FAQs

Our application is large. Does everything migrate in one sprint?

A scoped slice does; the assessment sizes the whole. Each sprint delivers a releasable increment, and the residual map shows exactly what remains, so progress is real rather than deferred.

What about WebForms or WCF components?

The parts with no direct modern equivalent are the strangler-fig candidates: replaced incrementally behind stable interfaces. The assessment identifies them and prices the options honestly.

We are not sure where to start across our estate.

Start with the Modernization Roadmap Sprint, which stages the whole estate; this package then executes the .NET workstream it identifies.
