Has your Objective-C app not been updated in two years? Want to move from Cordova to Flutter but afraid of losing users and data? Mobile app migration is a transfer between platforms and stacks without stopping the product. We preserve your audience, data, and business logic.
Mobile app migration is moving an existing product to a new technology platform or stack. We do this without data loss, user loss, and with minimal downtime.
Cross-platform migration — transfer from native platforms to cross-platform and back while preserving all scenarios. Move from Objective-C to Swift or Java to Kotlin without stopping development.
Architecture update — we rewrite legacy code while preserving business logic, perform UI redesign. Transition from MVC to MVVM or Clean Architecture.
Data migration — seamless user data migration between platforms without loss. We migrate SQLite to Realm or Cloud Firestore with integrity verification.
Zero-downtime process — the app remains available at all migration stages, with step-by-step auditing. Canary releases and feature toggles — retention stays stable.
iOS · Android · Flutter · React Native
Every project is unique, but we have identified three main migration scenarios our clients face most often.
Cordova → Flutter / React Native, Objective-C → Swift, Java → Kotlin. We preserve 100% functionality and improve performance by 2–5x.
MVC → MVVM / Clean Architecture. Adoption of reactive approaches — time to ship a new feature is reduced by 30–50%.
Data migration between databases and cloud providers with integrity guarantees. ETL pipelines with verify scripts — not a single byte lost.
Encryption in transit, backups at every stage, instant rollback. Data is protected from old infrastructure to the new stack.
Migration is not rewriting from scratch. It is product evolution, where we preserve what works and replace what is outdated. Our goal is that users do not notice the changes, while developers get a modern stack.
Migration is not just code. It is a comprehensive effort involving data, infrastructure, team, and users. We cover all aspects of transitioning to a new stack.
Zero-downtime migration — Strangler Fig strategy with gradual module replacement. Can be combined with redesign.
Post-migration testing — regression testing and A/B comparison of metrics before and after. New code doesn't go to production until it catches up to the baseline.
Web platform integration — backend migration with API contract preservation. Old endpoints run in parallel with new ones.
CI/CD and infrastructure update — build and deploy pipelines with linters, static analysis, and unit tests built into the pipeline.
Documentation and knowledge transfer — architecture, API contracts, and audit for your team. Workshops for independent product development.
Post-migration audit — performance and security check with a before/after report and metrics.
We guarantee the migration will go smoothly without data or user loss. A phased approach, continuous testing, and rollback capability at every stage. You can also order a redesign and audit of your app before and after migration.
Ordering mobile app migration means getting an up-to-date tech stack without losing your current audience and with minimal risks.
Encryption, integrity, backups at every stage. Each stage is verified with checksums and automated tests.
Smooth transition without downtime — users never lose access to their accounts. Retention stays at the same level.
We support the product for 30–90 days after migration: stability monitoring, optimization, and knowledge transfer.
Migration does not have to be scary. The right approach is phasing, test automation, and constant user feedback. We do migration so that no one remembers it a week after completion.
