What happens to your home folder when you upgrade to iCloud Drive?
When you upgrade an iCloud account to use iCloud Drive, you won’t be able to directly access documents from OS X Yosemite 10.10 or earlier or iOS 8 or earlier.
If you’re using OS X Yosemite 10.10 or earlier, you can still access iCloud Drive items from the iCloud website: icloud.com.
If you have iCloud Desktop & Documents enabled on one Mac and you enable it for another Mac, what happens to the user’s Desktop and Documents folders?
If you turn on iCloud Desktop & Documents on additional Mac computers, the Desktop and Documents content from those Mac computers is moved into subfolders inside the iCloud Desktop and Documents folders.
For example, adding another Mac named “MyMac” results in Desktop and Documents folders containing “MyMac—Desktop” and “MyMac—Documents.”
What happens to the user’s Desktop and Documents folders if you disable iCloud Desktop & Documents?
When you disable iCloud Desktop & Documents, the items are moved into a subfolder within iCloud Drive, and the local Desktop and Documents folders are created as new empty folders for the local user.
Users must navigate to iCloud Drive and manually copy their files to the new (empty) Desktop and Documents folders.
