HIGH SIERRA
  1. The only drive that is automatically converted to APFS when installing High Sierra is the boot drive IF and only IF it is a Solid State Drive. (A Fusion Drive is NOT a solid state drive even through there is a solid state component.)
  2. APFS is not supported on Fusion drives in High Sierra
  3. I have encountered no problems cloning an APFS volume using CCC 5.1.2 or its predecessor.
  4. To the best of my knowledge the only Volume repair utility currently available for an APFS volume is Apple's Disk Utility > First Aid.

MOJAVE
  1. In Mojave APFS on Fusion Drives will be supported, but whether or not that conversion for the boot drive will be automatic is TBD.
  2. Whether or not Time Machine will be supported on an APFS volume is TBD.
  3. Whether or not APFS will be supported on RAID arrays is TBD.
  4. If and when Diskwarrior, Drive Genius, and TechTool Pro will support volume repair on APFS volumes is TBD.
