SP tools work from your NEW J25 site. You enter the Database credentials from your J15 site, enter your new site PULLS the infos from your old database. There is no tool installation in your J15 site.
Its mentioned in SPupgrade FAQ and Docs. I never touched SPtransfer, and you are right... there seems to be no explicite information if it is a J25+ transfer tool only?! Please, ask the official support.
Good luck.
