If your iMac will run Sierra, you can upgrade directly via App Store. But, Yosemite is no longer offered. My early 2009 MacBook will not run Sierra and I had to take the torturous route through all the OS's to finally get to El Capitan (10.11.6). I did it to run the latest browsers.

I would have preferred Yosemite, which was as good as Snow Leopard to my mind, but my old Yosemite installers are no longer verified by Apple and can't be used. Nor can it be found among my previous purchases in the App Store. Good luck with that one...
