I'm working on transferring one of our teams in our Google Apps for Education domain to Google Team Drive but I'm running into a problem with files owned externally. A little background and elaboration:
Our organization hires seasonal employees that make use of and edit a shared curriculum, to try and limit ownership issues with such a high turnover rate we used a 'shared' account. For example [email protected]. This account owns the vast majority of the documents in it's drive but occasionally employees have created documents using their personal gmail accounts. When I try to migrate [email protected]'s folders and files to Team Drive I get an error because some of the files aren't in my domain.
I'm trying to find a way to search for these files so I can either copy them or delete them prior to transferring folders to Team Drive. Also open to other suggestions
