I'm assuming apple file system is only enabled if you do a fresh install right? Or is there an option to switch to it during the upgrade process?

  My understand is (haven't tried it yet) that the conversion happens automatically but only if you have an SSD.

    To be precise, a non-Fusion Drive SSD. Fusion Drives have been dropped for now.

  your filesystem will be automatically changed to APFS, no need to reinstall (Apple did this already with the iPhone as well)

    Is this something that I want? My gut feeling is that I don't want a brand-new file system...

      Sure, it has a lot of upsides, like copying of large files happening within an instant.

  Don't know how it works for the macOS upgrade, but the iOS 10.3 upgrade converted all existing filesystems to APFS in-place.
