Transfer Drive files to a new owner from Deleted user

Transfer ownership

In your Google Admin console (at admin.google.com)...

Go to Apps > G Suite > Drive and Docs.

Click Transfer ownership.

Note: You need the Drive service privilege and the Data Transfer privileges to see this option.

In the From field, enter the current owner’s username and select their domain.

In the To field, enter the new owner’s username and select their domain.

Click Transfer Files.

The files are automatically added to the new owner’s Drive. They appear in a folder named with the previous owner’s email address.

The original owner can still edit the files, unless their account is deleted or their permissions are changed.

Do not suspend the new owner's account during the transfer.

An email is sent to the administrator, and to the new and old owners.  The email describes if the transfer succeeded or failed.
