Apple Introduces Purchase Migration Between Accounts

The new feature allows users to consolidate digital purchases from a secondary Apple Account to their primary account, though with regional and procedural limitations.

Apple's new tool lets users transfer apps, music, movies, and other digital purchases from a secondary Apple Account to a primary Apple Account.
The migration process requires both accounts to be signed in on the same device, with two-factor authentication enabled and accounts set to the same country and region.
The feature is unavailable in the European Union, United Kingdom, and India, and secondary accounts must not participate in Family Sharing or have a remaining balance.
Once migration is complete, the secondary account can no longer be used for purchases, and payment methods and subscriptions are transferred to the primary account.
Apple provides a detailed support document to guide users through the process, which can be initiated via the Settings app on iPhone or iPad.
