Have one I cloud created a long time ago, my husband recently switched to apple and created another one for him we would like to combine the contents, already tried family sharing but we can only share recent contents, some the really old stuffs like from 5 years ago cannot be find on the phone cloud even thought it is in the Apple laptop cloud that is my first account.
You can't merge Apple (iCloud) IDs. Family Sharing or using the same ID are the only choices. It isn't recommended to share an Apple (iCloud) ID.
Family Sharing - If you don‘t see your family‘s shared content
If it is really old it is probably DRM protected media. You would have to subscribe to Match for one year to upgrade it to non-DRM which can then be shared. I know Apple Music has a Match component to it but I do not know if it allows for this upgrading element.
How to merge two IClouds accounts????
