What is the best way to migrate legacy App Store metadata formats for iOS apps?▼

Legacy App Store metadata migration is performed by exporting, validating, and importing metadata using the asc migrate commands, ensuring version-specific fields and character limits are correctly validated for iOS and watchOS apps.

Can I update app-level fields like name and subtitle across different locales?▼

App info localizations allow you to manage app-level fields such as name, subtitle, and privacy URLs across locales, validating required fields and ensuring character limits are met before uploading to App Store Connect.

Batch .strings uploads are supported for version-specific localizations, allowing you to download all localizations for a target version, translate them, and upload the updated files for multiple languages in a single step.
