I have three questions in regard to an upgrade to C1 8:
1. Do I have to first remove C1 7 before the upgrade? Or do I just install it on top?
2. What do I have to do so the old catalogs from C1 7 transfer well to C1 8?
3. I'm on Mavericks, and don't see a reason to upgrade to Yosemite (so many bad reviews on Apple's site - my MacBook Pro is running perfectly, so why risk it?).
