That seems like a clunky and time consuming way to do it. I would rather not have to buy another 1TB SSD, clone the Mini 256GB drive on to it, and put that in the Mini, then mount the iMac drive as an external drive to the Mini and then start copying over my data to the new drive. I have way more that 256GB of data on the iMac, so I can't migrate the iMac data to the smaller drive. Would there be anything on the iMac drive that would prevent High Sierra from detecting the hard ware changes (i.e., it was on an iMac and now it's on a Mini) and booting up successfully?

I would like to just swap out the drives in the Mini, but I don't know if that will work. I have a Mac Mini coming in that has a 256GB drive in it.

I have a 1TB SSD that I'm using on my iMac (mid-2011 running High Sierra). Swap Mac Mini SSD with SSD from iMac? Hi all,
