I recommend using an external drive with a backup created "just before" you unpack the new Studio and set it up.
I would use either SuperDuper or CarbonCopyCloner. Both are FREE to download and use for 30 days and neither will cost you to do this job.
Time machine will work, too, but I've never used it, not ever.
DO NOT set up the Studio without attaching the backup first.
A MISTAKE some folks make is to turn on a new Mac, create a NEW account, and then try to migrate their OLD account over from a backup. The Mac will see these as "2 DIFFERENT accounts" (and you'll have permissions problems).
With the backup ready, set up the new Studio.
Connect the backup.
Now, press the power on button for the very first time.
Begin setup.
Setup assistant will ask if you wish to migrate - YES you do.
Just "point the way" to the backup and give SA time to digest everything on it.
SA will present you with a checklist of stuff to migrate.
Default way is just to migrate everything.
However...
When a friend set up a new Studio from his old 2012 Mini, I suggested he migrate everything EXCEPT applications.
He had a cloned backup, so I suggested that once the migration of everything else was done, he could try running the apps directly from the cloned backup (because all the preferences and other data "got migrated" with his account).
This way, he could try apps BEFORE copying them over to the new Mac.
He said this worked out well.
Good luck.
