# AppMigrationKit One-time cross-platform data transfer for app resources. Enables apps to export data to or import data from another platform (for example, Android) during device setup or onboarding. AppMigrationKit APIs are iOS 26.0+ / iPadOS 26.0+; the data-container entitlement is iOS 26.1+ / iPadOS 26.1+ / Mac Catalyst 26.1+. Swift 6.3. > **Beta-sensitive.** AppMigrationKit is new in iOS 26 and may change before GM. > Re-check current Apple documentation before relying on specific API details. AppMigrationKit uses an app extension model. The system orchestrates the transfer between devices. The app provides an extension conforming to export and import protocols, and the system calls that extension at the appropriate time. The app itself never manages the network connection between devices. ## Contents - [Architecture Overview](#architecture-overview) - [Setup and Entitlements](#setup-and-entitlements) - [App Migration Extension](#app-migration-extension) - [Exporting Resources](#exporting-resources) - [Importing Resources](#importing-resources) - [Migration Status](#migration-status) - [Progress Tracking](#progress-tracking) - [Testing](#testing) - [Common Mistakes](#common-mistakes) - [Review Checklist](#review-checklist) - [References](#references) ## Architecture Overview AppMigrationKit operates through three layers: 1. **App extension** -- An `AppMigrationExtension` conforming type that the system invokes during migration.
