It is clear that if you format you drive to APFS rather that convert a HFS+ drive to APFS you will have less problems in the long run.  My question is if you have a fusion drive and are upgrading from High Sierra to Mojavi, what are the steps you need to do this.  I have 2 superDuper! clones of my High Sierra startup drive.  Normally I would just boot from the clone and format the internal drive as an APFS volume.  But I it seems I cannot format a fusion drive as APFS from High Sierra!.  What is the simplest way to accomplish this task?  Let the discussion roll on.

I guess you'd have to boot from one of your clones, run the Mojave installer from there, and launch Disk utility from there where you would have the option to format the local drive to APFS and install Mojave after. It's worth a try.
