I used a Time Machine backup to migrate my Mojave MacBook Pro to my new Monterey M1 16" MacBook Pro. All of the files/folders that used to be on the startup disk top level are gone. All I have now is Users, Library, System and Applications. Any idea how to get them back?
Welcome to the Apple Support Communities.
Starting in macOS Catalina, macOS uses a read-only system volume and user's files cannot be stored at the "root" or "top level" of your startup disk: About the read-only system volume in macOS Catalina - Apple Support.
Look for the files in a "Relocated Items" folder in the Shared folder within the User folder (/Users/Shared/Relocated Items), or for the alias on your desktop.
If they are not there, choose a new destination for these files, then use your Time Machine backup to Restore items backed up with Time Machine on Mac - Apple Support to the new location.
