Apple Merging ‘iCloud Documents and Data’ Service With iCloud Drive in May 2022

Apple prepares to merge its iCloud Documents and Data service with iCloud Drive starting in May of 2022, according to a support document released late recently (via MacGeneration).
iCloud Drive and iCloud Data and files share the basic ability to backup information from apps. Nevertheless, iCloud Data and documents was frequently a troublesome, confusing experience. In contrast, iCloud Drive is more merged, with users able to access their files and content through the Files app across all their devices.
As Apple discusses, starting in May of next year, users who are using iCloud Documents and Data will have their accounts instantly moved to iCloud Drive. Users should manually allow iCloud Drive to see their files once the merger occurs.
In May 2022, the iCloud Documents and Data service, our former document synchronization service, will be cut off and entirely changed by iCloud Drive. For that reason, if you use iCloud Documents and Data, your account will be moved to iCloud Drive after that date.
You should trigger iCloud Drive by following the steps below to view your files if you use the iCloud Documents and Data service. Updating to iCloud Drive does not change the storage space utilized by your files saved in iCloud.
iCloud Drive launched in 2014 as a merged, smooth method for Apple users to keep all their files, documents, and more integrated across all their devices. To trigger it, users on iOS or iPadOS gadgets can go to Settings -> > iCloud and enable iCloud Drive, or through System Preference -> > iCloud, and select iCloud Drive on macOS.
