Is it possible to migrate between AppleIDs?

Question

Apple ID

Not a fan of MacOS and with the technique of this manufacturer on "You" or even on "Your Majesty".
Essence of the question:
There is an appleID for example [email protected] and files on it in different places. You need to transfer all files from the AppleID with the name [email protected] to the new [email protected], and then delete the old one.
There are no problems with the second option. I go to the site, delete the account, and then logging in under the new appleID on the poppy, I delete the old account from the system. How to transfer data without using a flash drive? Essentially how to merge.

Answer 1

The apple id and the content associated with it are in no way considered unique by the company. Flash drive only, hardcore only
