Apple One does provide an option to help users manage multiple Apple IDs stored in iCloud, but it cannot solve a long-standing problem and it does add confusion.
Some Apple users’ iCloud accounts and their App Store and Services subscriptions have different Apple IDs. This is because Apple’s cloud-based services and iTunes-related subscriptions were initially separate.
Back in September, Apple employee Chris Espinosa said that Apple One “managed” such situations. Since the bundled service debuted on Friday, it seems to alleviate the problem but not solve it.
During the Apple One registration process, the user will be prompted to select the option to associate the Apple One storage it contains with the Apple ID currently used for iCloud. This means that users will get the amount of storage that comes with Apple One on their iCloud Apple ID, and the initial iCloud storage plan will be cancelled (although their data will remain the same). Other bundled Apple One services will be associated with the user̵
Of course, this solution does not involve merging or merging accounts. It only solves the problem of having separate Apple IDs for iCloud and App Store and iTunes.
Users can also choose to associate their Apple One iCloud storage with their main iTunes and App Store accounts. In this case, storage for each account will be handled separately.
At least one Twitter user said that they chose to use an iTunes/App Store account to store Apple One. When they do, it will automatically cancel its iCloud Apple ID storage plan. After that, all the data in that storage was reported to be displayed in his Apple One account.
I have the same. When I choose to switch to Apple One iCloud storage, it will automatically cancel my iCloud account storage plan, and all data in that storage will be displayed in my Apple One account iCloud storage.

Apple insider Can’t verify if this is common, and can’t replicate it myself. This may just be the case where the user device uploads its data to iCloud according to the new plan, rather than actually transferring the data from one Apple ID to another.
Although the options here will help users with multiple Apple IDs actually sign up for the service, it’s a far cry from the simple account merging or merging that users have been asking for.
Update: Since the publication of this article, Apple insider It can be confirmed by sources within Apple that it is still impossible to merge two separate Apple IDs.
