For the OP. I think this is unsupportable because Fedora 17, 18, 19, 20 aren't supported. And as mentioned, one of those moved from preupgrade to fedup, and fedup is fundamentally flawed which is why it's going away in Fedora 23. It's sufficiently fundamentally flawed in the edge case scenario (i.e. not a simple default installation or one sufficiently common that's known to work, which does NOT really include raid1 + separate usr, I had lots of problems with this and fedup when I was doing testing) that it's just not even worth attempting in my opinion. The installer (Anaconda) should recognize all of the various parts including the separate usr and raid1, and let you reuse what you want and blow away what you don't want. It's been sufficiently long since Fedora 16 that you should get new file systems for everything. The installer enforces this for / although I'm not sure if it's enforced for /usr. It's not enforced for /home. Anything on Btrfs created more than a year ago should bite the bullet and reformat. It's just a much more deterministic outcome that way.
