1. Move the files you wish to transfer from first Google account ( G1 )  ( including folders ) into a single folder in Google Drive.
2. Share this folder with second Google account ( G2 ).
3. Log in to G2.
4. Move the folder from “Shared with Me” to “My Drive”. This folder is still owned by first Google account ( G1 ) and you cannot change the ownership from second Google account ( G2 ).
5. Download Google Backup and Sync ( https://www.google.com/drive/download/backup-and-sync/ ).
6. Install Google Backup and Sync.
7. Once you have installed the tool, log in using second Google account ( G2 ) and wait until the drive completely syncs.
8. Locate the shared folder and right click on it.
9. Click on Duplicate. This will create a copy of the folder with second Google account ( G2 ) as the owner of the folder and all its contents.
10. Wait for this new folder to sync with the Google Drive. Check the Drive folder and you should now see that the G2 is the owner of the copied folder and all its contents.
