React Migration in Lichfield
Migrating Lichfield applications to React, incrementally rather than as a rewrite. The old application contains years of accumulated handling for cases nobody documented — the awkward customer, the legacy data shape, the browser quirk — and a rewrite from the specification reproduces the intended behaviour while losing all of that.
Why this comes up
The problem
A full rewrite was scoped, and the existing application handles a hundred edge cases nobody has written down.
What you get
What we deliver
- Migration route by route, with old and new running alongside each other
- A boundary where the two coexist without fighting over the page
- Shared authentication and session so users never notice the seam
- Existing behaviour captured as tests before the code that produces it is replaced
- Design system introduced progressively rather than as a simultaneous redesign
- The old application actually removed, section by section, as each is replaced

Thirty minutes, no charge, no sales script. You leave with a written summary of what react migration would actually involve — whether or not you use us.

React Migration in Lichfield — common questions
- Why not rewrite it properly?
- Because the specification is not the application. Years of small fixes for real situations are embedded in code and absent from any document, and a clean rewrite delivers something that works for the common cases and fails for customers who had been fine.
- How do old and new coexist?
- By dividing at a boundary — route by route is usually cleanest. Each migrated section is complete in itself, users move between them without noticing, and the shared concerns are authentication, session and enough styling that it does not look like two applications.
- Should we redesign at the same time?
- Preferably not. Changing the technology and the interface together means any complaint could be either, and it doubles the scope of a project that is already about reducing risk. Migrate first, then redesign with a codebase that makes it straightforward.
- How do we avoid running both forever?
- Remove the old section as each replacement goes live, and treat the final unglamorous parts as part of the project rather than a phase two. Migrations stall at the last twenty per cent, and running two applications indefinitely is worse than either.
- Do you work with businesses across Staffordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Lichfield and the surrounding Staffordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Lichfield businesses do you usually work with?
- Small professional practice systems — booking, invoicing and client portals for firms with a regional rather than local client list. Beyond that we work across Retail, Tourism & Heritage, Professional Services, Logistics and Construction.
- Do you cover the areas around Lichfield?
- Yes — we work throughout West Midlands, including Birmingham, Stoke-on-Trent, Wolverhampton. Lichfield is an urban area of roughly 35,000+, and we take on work across the wider Staffordshire region rather than the city boundary alone.
