React Native Migration in Belfast
React Native version migrations for Belfast organisations, where the work is rarely in your own code. Framework upgrades change native build configuration, and the blockers are third-party modules that have not been updated — so the migration is largely an exercise in resolving other people's dependencies against a moving target.
Why this comes up
The problem
The framework upgrade is straightforward and four native modules will not build against the new version.
What you get
What we deliver
- Every native dependency assessed against the target version before starting
- Blocking modules replaced, forked or removed as an explicit decision
- Build configuration changes applied on both platforms and verified
- Architecture migration handled where the framework requires it
- One version at a time where the gap is large, rather than a single jump
- The app exercised on real devices, since build success is not sufficient

React Native Migration in Belfast — common questions
- Why are native modules the blocker?
- Because they contain platform code compiled against framework internals. When those change, the module must be updated by its maintainer — and if nobody is maintaining it, you inherit the work or find something else that does the job.
- Should we jump several versions?
- Only where the gap is small. Across a large distance the changes interact, and a failure has too many possible causes to diagnose efficiently — stepping through versions is slower in total and far more predictable.
- Is a successful build enough?
- No. Upgrades change runtime behaviour, and modules can compile while behaving differently — so the app needs exercising on real devices across the main flows before anyone concludes the migration worked.
- What if a module has no replacement?
- Then it is a decision rather than a technical problem. The options are forking and maintaining it, writing a native module yourself, or dropping the feature — and choosing deliberately early is considerably better than discovering it mid-upgrade. Each option carries an ongoing cost, so the choice belongs with whoever owns the product rather than with whoever is doing the upgrade.
- Do you work with businesses across County Antrim?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Belfast and the surrounding County Antrim area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Belfast businesses do you usually work with?
- Fintech and security-accredited systems, plus trading platforms that handle the specific customs position on goods. Beyond that we work across Fintech, Cyber Security, Film & Media, Manufacturing and Higher Education.
- Do you cover the areas around Belfast?
- Yes — we work throughout Northern Ireland, including Lisburn, Bangor, Newry. Belfast is an urban area of roughly 345,000+, and we take on work across the wider County Antrim region rather than the city boundary alone.
