If you backup your new Mac, you'll have every thing on the Mac. If you're worried about history, its importance to you will determine what you do.


HDDs are cheap and reliable. If you wish to sequester the historical data, get a new HDD and start afresh keeping the old drive in a safe place. How often you've used historical data should help determine its usefulness.
