Updating to High Sierra on a new iMac
I am going to be purchasing a new iMac with a Fusion HD from Best Buy that comes with Sierra installed, not High Sierra
Which would be better:
Upgrade the new iMac to High Sierra before I migrate my files from my old iMac which is running I think Mavericks?
Or migrate from my old computer and then update to High Sierra?
My thinking is that if I do the upgrade before the migration, I save myself having to do a backup
