EASIEST WAY TO TRANSFER FILES FROM OLD MAC TO NEW MAC REGISTRATION
Many software companies tie the registration to the disk or Mac it's installed on to reduce piracy, so some applications may need to be re-registered. Once you have migrated data with Apple's Migration Assistant, there will be some housekeeping to perform.

Apple Kbase #HT2186: Use the Mac operating system that came with your Mac, or a compatible newer version.Can I restore my Mac's backup to another computer?.After Migration Assistant has completed, then you can move the SafetyNet folder back to the root of the backup volume. If you would like to retain the SafetyNet folder on the backup volume, don't empty the Trash. This is particularly important if that folder has a lot of data in it and you're migrating to a disk that is smaller than the backup volume. If your backup volume has a "_CCC SafetyNet" folder, you can move that folder to the Trash before using Migration Assistant to avoid copying that folder during a migration. Migration Assistant and the CCC SafetyNet Once you have migrated your user accounts and applications using Setup Assistant or Migration Assistant, you can continue to use CCC to back up your Mac to the same backup volume that you were using for the old Mac. You can migrate directly from a CCC backup of your old Mac.

We recommend that you use the Setup Assistant application (runs on your Mac's very first boot) or the Migration Assistant application to migrate content from your old Mac to a new Macintosh. Your new Macintosh cannot boot from the older version and build of macOS that is installed on your older Mac, so simply restoring your old Mac's backup onto your new Mac won't work. When you get a new computer from Apple, it has a specific version of macOS installed on it, and further, a hardware-specific "build". Use Setup Assistant or Migration Assistant to migrate data from a CCC backup to a new Mac
