When the data transfer begins, Migration Assistant will display a progress bar with an estimate of the remaining time. Transfer time is highly dependent on the items you selected, and the amount of data you’re copying.
Time estimates tend to be over-inflated initially; the actual transfer time is usually much shorter. Once the progress bar hits the one-third to halfway point, the remaining time estimate becomes more accurate.
Migration Assistant will let you know when the information has been transferred successfully. Click the ‘Continue’ button to quit Migration Assistant.
Although Migration Assistant doesn’t require you to restart your Mac, it’s generally a good idea to do it anyway. In many cases, transferred items may need to be initiated at startup in order to work correctly.
A Word About Application Licenses
Applications that you transfer using Migration Assistant should, for the most part, work without re-entering licensing information, but there’s no guarantee that every application will be accommodating.
Some applications base internal license keys on physical hardware attributes. If you run them on a different hard drive, you may need to provide the registration information again. Other applications hide license files in strange locations that Migration Assistant might miss. So, have the registration information for all of your applications on hand, just in case.
