Typically, a Mac owner will perform an in-place upgrade from High Sierra to Mojave. This will obviate the need for any kind of migration, and all software licenses will continue to work.@CaseySJ,
I just gave it another read and was thinking that technically based on your thought 'whole system' type backups from time machine get invalidated once Mojave is in place. They are still good, but just for cherry picking (files, folders, etc ..). I'm wondering how it would have been done on a real Mac, through Migration assistance only?
But if High Sierra and Mojave are on two different disks, then we cannot restore from Time Machine backups. We have to use Migration Assistant or simply migrate our data and applications manually.
So another option is to clone the High Sierra system to a new disk and perform an in-place upgrade to Mojave on that disk.
