Fixed-price .NET migration audit · UK
We audit your legacy .NET codebase and deliver a written report a budget holder can act on: what it will take to reach modern .NET, where the risks are, and what order to do it in. £499 fixed, whatever we find. Delivered within 5 working days of repo access.
What you get
The report is the product. It stands alone — plenty of clients take it and run the migration with their own team.
Every project, framework version, and language variant in the estate, mapped. Including the apps nobody remembers deploying.
The blockers that derail migrations: dependencies with no modern equivalent, business logic buried in UI event handlers, undocumented integrations.
Third-party packages, internal couplings, and databases, graded by migration difficulty.
A realistic range in developer-weeks, grounded in two decades of delivering these migrations — not a tool's guess.
What to migrate first, what can wait, and how to do it without the business noticing.
Where containerisation, cloud services, or a WinForms-to-Blazor rebuild pays for itself — and where it doesn't.
How it works
You tell us what you've got and what's making migration feel risky. If the audit isn't the right fit, we'll say so on this call.
Git access to the relevant solutions. Read-only, under NDA if you want one. No agents installed, nothing runs in your environment.
A written document plus a walkthrough call. Questions answered until you're confident presenting it internally.
Principal-led, always.
Every audit is performed end-to-end by our principal consultant — 21 years of .NET delivery across rail freight, financial services, and mortgage platforms. No juniors, no offshoring, no handoffs.
Pricing
£499 fixed
One price, whatever we find. No day rates, no scope creep, no retainer.
If the report doesn't give you a clear, costed path forward, you don't pay.
