How to upgrade from iCloud Documents and Data to iCloud Drive
iCloud Documents and Data, our legacy document syncing service, has been discontinued and replaced by iCloud Drive. If you used iCloud Documents and Data, your account has been migrated to iCloud Drive.
If you used the iCloud Documents and Data service, you need to turn on iCloud Drive to see your files. When you switch to iCloud Drive, the amount of storage space your saved files use in iCloud doesn't change.
What is iCloud Drive?
iCloud Drive allows you to easily store, access, and share files with friends and family. Documents that you store in iCloud Drive stay up to date across all of your devices, and you can access them from your iPhone, iPad, iPod touch, Mac, or PC, and on iCloud.com.
