FAQ

Migration FAQ

Clear answers before you commit to the migration.

How long does the migration take?

After the audit, you get a phased plan with clear milestones. Timelines depend on app complexity and native surface area.

What if a native dependency isn’t Expo-ready?

Each module is audited, replaced or adapted with Expo-compatible alternatives, and backed by documented fallback paths.

Can the team keep shipping during the migration?

Yes. The migration is staged to protect release cadence and reduce risk.

Is Expo workflow optimization included?

Yes. EAS Build/Submit/Update, versioning, and QA distribution are part of the fixed-fee scope.
