.NET Migration in Gloucester
Migrating Gloucester applications from .NET Framework to modern .NET, where the first task is finding what has no successor. Several Framework technologies were not carried forward — server-side WCF, Web Forms, remoting — so an application built on one of those is facing a redesign of that layer rather than a port of it.
Why this comes up
The problem
The migration was estimated as a port, and a third of the application is built on a technology that no longer exists.
What you get
What we deliver
- Technologies without a direct successor identified before anything is estimated
- Replacement approach chosen for each, since the alternatives differ substantially
- Incremental migration behind a proxy where the application is too large to move at once
- Dependencies assessed for modern .NET support, including transitive ones
- Configuration and hosting reworked, as the models differ meaningfully
- Behaviour captured as tests before the layers producing it are replaced

.NET Migration in Gloucester — common questions
- What genuinely does not port?
- Server-side WCF, Web Forms and remoting are the main ones. Clients and alternatives exist for some, and the honest position is that these represent a redesign of that layer — which is why finding them early matters more than any other assessment step.
- Can a large application move incrementally?
- Yes, by routing traffic through a proxy that sends migrated paths to the new application and everything else to the old one. Each release moves a section, both run together, and the migration proceeds without a single high-risk cutover.
- How do we handle dependencies?
- Audit them including transitively, because one unsupported package deep in the graph can block everything above it. Most widely used libraries have moved; the ones that have not are usually internal or long abandoned, and both need a decision.
- Is it worth doing at all?
- For an application under active development, generally yes — performance, hosting options and access to current tooling. For a stable system nobody is changing, the Framework remains supported and the migration may be effort spent for benefits nobody will use.
- Do you work with businesses across Gloucestershire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Gloucester and the surrounding Gloucestershire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Gloucester businesses do you usually work with?
- Aerospace and manufacturing supply chain systems, with security and accreditation questions arriving in the first meeting. Beyond that we work across Aerospace, Manufacturing, Financial Services, Logistics and Cyber Security.
- Do you cover the areas around Gloucester?
- Yes — we work throughout South West, including Bristol, Worcester, Bath. Gloucester is an urban area of roughly 150,000+, and we take on work across the wider Gloucestershire region rather than the city boundary alone.
