Question 1

How do I upgrade my Expo SDK version?

Accepted Answer

At a high level, you create a clean branch, bump the Expo SDK with the upgrade helper, align your native dependencies to SDK-compatible versions using expo install, fix any breaking changes the changelog calls out, and then rebuild and test on both iOS and Android. The recommended sequence is: commit or branch your current working state, run npx expo install expo@^TARGET to bump the SDK, run npx expo install --fix to realign packages, run npx expo-doctor to surface mismatches, update your app config, plugins, metro, and babel as needed, and finally clear caches and do a full device test. For small jumps of one SDK version you can usually upgrade directly. For larger gaps, upgrade one SDK version at a time and test in between, because skipping versions compounds the breaking changes you have to handle at once. Always follow the official Expo upgrade guide and read the changelog for each version you pass through.

Question 2

Should I upgrade Expo SDK one version at a time or jump straight to the latest?

Accepted Answer

It depends on how many versions you are skipping and how many native dependencies you use. For a single SDK hop, a direct upgrade is usually fine and faster. For gaps of two or more SDK versions, an incremental upgrade — moving one version at a time and testing between each step — is safer. The reason is that each Expo SDK release pins a specific React Native version and introduces its own breaking changes and new defaults. When you jump several versions at once, all of those breaking changes hit you simultaneously, which makes it much harder to isolate what broke. Incremental upgrades let you fix and verify one version of changes before moving on, so when something breaks you know exactly which release caused it. Apps with heavy native modules — animations, notifications, maps, payments, or anything affected by the New Architecture — benefit most from the incremental approach. This planner recommends a path strategy based on the size of your version gap and the libraries you list.

Question 3

What are the most common breaking changes when upgrading Expo SDK?

Accepted Answer

The breaking changes you hit depend on which versions you pass through, but the recurring ones include: the New Architecture (Fabric and TurboModules) becoming the default, which can break libraries that have not adopted it; major versions of expo-router that change file conventions and APIs; major versions of react-native-reanimated that change the worklet and plugin setup; changes to expo-notifications and push handling; removed or extracted modules that you now install separately; and updates to the config plugin, metro, and babel setup. React Native itself also ships breaking changes between versions, since each Expo SDK bumps the underlying RN version. The safest approach is to read the official Expo changelog and upgrade guide for every version in your path, run npx expo-doctor to catch dependency mismatches, and test on real iOS and Android devices rather than just a simulator. This tool surfaces the breaking changes most relevant to your specific version range and the libraries you mention.

Question 4

How long does an Expo SDK upgrade take?

Accepted Answer

A single-version upgrade on a small app with few native dependencies can take just a couple of hours, mostly bumping versions and a quick regression test. A larger jump across several SDK versions, or an app with many native modules, can take a day or more once you account for fixing breaking changes, updating config, resolving library incompatibilities, and testing on both platforms. The biggest time sinks are usually native dependency conflicts, migrating across a major expo-router or Reanimated version, and adopting the New Architecture. Effort also scales with how thoroughly you test — apps with critical flows like payments or real-time features need more verification. This planner gives a realistic hands-on hours range based on your version gap and dependencies, but treat it as a starting estimate. Upgrading on a dedicated branch, doing it incrementally, and keeping your dependencies current between SDK releases all reduce the time each upgrade takes.

Question 5

How accurate is this Expo SDK upgrade planner?

Accepted Answer

This tool produces a realistic, well-structured upgrade roadmap based on your described versions, libraries, and common Expo migration patterns, but it is a guide rather than an authoritative source. Expo releases evolve quickly, and exact version numbers, bundled React Native versions, and specific breaking changes should always be verified against the official Expo documentation and changelog for each SDK version in your path. The AI is strongest at structuring the work, sequencing the steps, flagging the categories of breaking changes to watch for, and estimating risk and effort — and it is intentionally cautious about inventing precise version specifics it is unsure of. Use the generated plan to organize your upgrade, brief your team, and avoid missing common steps like running expo-doctor or aligning native dependencies. Before running any commands, cross-check them against the current Expo upgrade guide, and always upgrade on a branch so you can roll back. The more detail you give about your current version, target version, and key libraries, the more tailored and useful the plan will be.

Question 6

Is it easier to upgrade an old Expo app or rebuild it?

Accepted Answer

It depends on how far behind you are and how much custom native code you have. Upgrading is usually the right call when you are one or two SDK versions behind, your dependencies are mainstream, and the app is actively maintained — the incremental path is well-trodden and fast. Rebuilding becomes attractive when you are many versions behind, rely on abandoned or incompatible native modules, or the codebase has accumulated significant technical debt, because each successive upgrade then fights the same legacy issues. With an AI app builder like RapidNative, rebuilding is far cheaper than it used to be: you describe the app and the AI generates real React Native code on the latest Expo SDK, so you start clean on current tooling and the New Architecture instead of dragging old patterns forward. A common strategy is to upgrade to stay current while you can, and reach for a fresh rebuild when the upgrade cost starts to exceed the value of the existing code.
