The first time you open Apple Configurator 2, if you’ve been using Apple Configurator 1, your settings will be upgraded from the old sqlite3 database in Apple Configurator 1 into the Apple Configurator 2 decentralized file structure. To get started, first backup your computer. I’d recommend a clone as with certs and profiles and databases and all that fun stuff. Once you have a solid backup, open the new Apple Configurator 2 app and then click on the Next button at the Introduction screen.
At the Library Migration screen, select each of the types of data that you’d like to migrate and click on the Next button.
At the Device Backups screen, you will have the option to select any backups that should be migrated to the new location and structure. Check the box for any you’d like to migrate and then click on the Next button (note, there weren’t any on this system as I’d removed them already).
At the Convert Device Configurations to Blueprints screen, you’ll have the option to save each of your unique configurations from Apple Configurator 1 (from the prepare screen) to what are now known as Blueprints in Apple Configurator 2. Select any that you’d like to convert and click Next.
This is a pretty small amount of data (well, other than backups and apps). You’ll then be shown what is going to get migrated. Click on Next if this is correct.
Finally, choose where it all goes.
Provided that all the data is migrated properly, you’ll then be shown a beautiful Migration Successful screen.
That’s it. Now you’ll be looking at the Getting Started screen.
