Modernisation & Consulting

Legacy .NET Modernisation & Consulting

Legacy systems often still run the business. We modernise them incrementally, moving to current .NET, cloud hosting and better architecture without a risky big-bang rewrite.

What we build

  • Legacy .NET Framework to modern .NET
  • Architecture reviews
  • Performance improvements
  • Cloud migration
  • Security improvements
  • Software architecture consulting

A good fit when

  • Systems stuck on old frameworks or unsupported servers
  • Applications that are slow, fragile or hard to change
  • Leadership needing an independent technical assessment

How we approach it

  1. 01

    Assess before rewriting

    A clear picture of what to keep, refactor or replace, with the reasoning behind it.

  2. 02

    Incremental migration

    Strangler-style modernisation that keeps the business running throughout.

  3. 03

    Practical recommendations

    Prioritised by risk and value, not by technical fashion.

Typical stack

  • .NET 10
  • ASP.NET Core
  • EF Core
  • SQL Server
  • Azure
  • Docker

FAQ

Modernisation & Consulting: common questions

Do we need to rewrite our legacy system?

Rarely all at once. Incremental modernisation replaces parts of the system over time while it keeps running, which is far lower risk than a big-bang rewrite.

Can .NET Framework applications move to modern .NET?

Yes. Most can be migrated to current .NET in stages, gaining performance, security updates and modern hosting options, including Linux containers and the cloud.

What does an architecture review include?

An assessment of code, data, hosting, security and delivery practices, with prioritised recommendations explaining the risk and value of each.
