I see that when I upgraded to Mavericks last year, I got the recent 'iMovie' app. And then after the update OSX left a folder called iMovie 9.0.9 in my hard drive. So I take it this is the older legacy version of iMovie. Since I had never used that version, could I just safely delete the folder and Trash it? The iMovie 9.0.9 does not appear in my Launchpad, only the newer 'iMovie' appears there. I'm afraid that if I (finally) upgrade to Yosemite 10.10.3, it will install the brand new Photo app, but leave like 3 legacy versions of iPhoto cluttering the HD.
