AngularJS to Angular Migration in Plymouth
Moving Plymouth applications from AngularJS to modern Angular, where the version numbers conceal that these are different frameworks. There is no upgrade path — components, dependency injection, templates and change detection all work differently, so the work is writing the application again with the old one as the specification.
Why this comes up
The problem
The application still runs on AngularJS, which stopped receiving support several years ago.
What you get
What we deliver
- Scope agreed as a rewrite, since estimating it as an upgrade guarantees an overrun
- Existing behaviour documented from the running application, not from memory
- A hybrid approach assessed, allowing both frameworks to run during transition
- Screens prioritised so the most valuable parts are modernised first
- Third-party dependencies replaced, as AngularJS libraries have no equivalents
- Tests written during the rewrite, because the old application probably lacks them

AngularJS to Angular Migration in Plymouth — common questions
- Why is there no upgrade path?
- Because the frameworks share a name and little else. Modern Angular was rebuilt from scratch with different concepts throughout, so existing controllers, directives and services do not carry over — treating this as a version bump is the most expensive misunderstanding available.
- Can both run at once?
- Yes, through a hybrid arrangement where screens are moved gradually. It costs more overall and carries complexity while both are live, but for large applications it is often the only approach that does not require the business to stop while a rewrite happens.
- Should we consider a different framework?
- It is a fair question, since the work is a rewrite either way. Angular is the natural destination for teams who know it, but the argument for staying is familiarity rather than reuse — and that is worth examining before committing rather than assumed.
- How urgent is this?
- It deserves treating as a live risk. AngularJS no longer receives security patches, and the dependency chain around it is similarly unmaintained — so an application handling anything sensitive is carrying an exposure that grows quietly with every year it remains.
- Do you work with businesses across Devon?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Plymouth and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Plymouth businesses do you usually work with?
- Marine and defence supply chain systems where security accreditation is a precondition rather than a differentiator. Beyond that we work across Marine & Defence, Manufacturing, Healthcare, Higher Education and Tourism.
- Do you cover the areas around Plymouth?
- Yes — we work throughout South West, including Exeter, Truro, Bristol. Plymouth is an urban area of roughly 260,000+, and we take on work across the wider Devon region rather than the city boundary alone.
