80–160 hours of senior engineer time. At $150–250/hr fully-loaded cost, that's $12,000–$40,000 in opportunity cost. This doesn't appear on any invoice — which is why teams consistently underestimate it.
Upgrades are deprioritized when a sprint gets busy. One engineer gets pulled in, spends two weeks on it, hands off incomplete, and the next person starts over. The upgrade drags on for months while features stall.
Your team includes a dedicated senior RN engineer with genuine upgrade experience, the app has no custom native modules, and the upgrade is a minor version bump. This is less common than most teams assume.
The obvious choice when you have bandwidth and expertise. The expensive choice when you don't — but it often takes months of spinning before teams acknowledge that.
$75–$200/hr depending on platform and location. For a 100–150 hour project, that's $7,500–$30,000+ — with an open-ended timeline. Most contractors bill hourly, so complexity overruns are billed to you.
React Native upgrade expertise is hard to verify on a platform like Upwork. Many contractors have done basic RN work but haven't handled native module conflicts, Hermes migration, or New Architecture — the things that cause real stalls.
You can personally vet the contractor's RN upgrade track record, the project scope is simple, and you have time to manage the engagement closely. Best when you have a trusted contractor relationship already.
Higher risk than it appears. The vetting problem is real — RN upgrade experience is specifically hard to assess from a profile or short interview.
$15,000–$50,000+, typically billed T&M or as a project estimate. Onboarding a new team to your codebase adds weeks and cost before actual upgrade work begins.
Most dev shops are generalists. React Native upgrades — particularly when they involve custom native modules, Expo, or the New Architecture — require specific pattern recognition that most agencies haven't developed. Complex upgrades get treated as T&M discovery projects.
The same agency already knows your codebase well from prior work, reducing the onboarding overhead. Less relevant if you're bringing them in specifically for the upgrade.
The most expensive option for upgrade-specific work, unless there's an existing relationship. Generalist approach means slower resolution of edge cases.
$5,997 (ESSENTIAL) to $9,997 (COMPLETE), fixed price. No hourly billing, no scope creep charges, no surprises. Typically less than the opportunity cost of a senior engineer doing it in-house.
We've handled hundreds of React Native upgrades. The edge cases that stall in-house teams — Hermes migration, CocoaPods conflicts, custom native modules, Expo SDK upgrades — are routine for us. We have playbooks, not discovery projects.
Full dependency upgrade, breaking change resolution, native build configuration, and a 14-day fix guarantee. NDA before code access. North America-based, in-timezone communication. Your team stays on their roadmap.
If your app is simple (Expo managed workflow, no native customization) and your team has bandwidth, DIY may be faster. We're most valuable when the upgrade is complex, time-sensitive, or has already stalled once.

No commitment required. We'll tell you honestly if we're the right fit.
It varies significantly by approach. DIY using in-house senior engineers runs $12,000–$40,000 in opportunity cost (80–160 hours at $150–250/hr), not counting deferred feature work. A freelance contractor: $8,000–$25,000+ on hourly billing. A dev shop: $15,000–$50,000+. A specialized service like React Native Rescue: $5,997–$9,997 fixed price, completed in 2–4 weeks.
DIY: 4–12 weeks when done in parallel with feature work, often dragging longer. Freelancer: 3–8 weeks depending on availability. Dev shop: 6–12 weeks. Specialized service: 2–4 weeks, with faster turnaround from repeatable playbooks for common scenarios.
In-house makes sense when you have a senior RN engineer with dedicated time and the app is relatively simple. Hiring out makes sense when your team is at capacity, you've already tried and gotten stuck, the upgrade involves native modules or the New Architecture, or there's a deadline. The hidden cost of DIY is opportunity cost — 80–160 hours of senior engineer time not spent on features.
A freelancer is typically an individual with variable upgrade experience. A specialized service focuses exclusively on upgrades and has developed repeatable playbooks for common scenarios: Hermes migration, New Architecture, custom native modules, Expo SDK upgrades. Specialization means fewer surprises, fixed pricing, and faster resolution when edge cases arise.
React Native Rescue is a specialized upgrade service run by North America-based senior engineers who have been shipping React Native apps since 2016. We handle React Native dependency upgrades and security audits at a fixed price with a 14-day fix guarantee. We work with Series B+ companies and enterprise teams that need the upgrade done right without diverting their engineers from feature work.
