Restore to a different, but identical Mac

[dnanian]

It came through, but after 10pm my time, so I didn't get to it until 8am or so. Sorry: I have to sleep every so often.

Anyway, here's what I said (slightly edited, since you've changed the phrasing and questions):

Well, it's not good that your data doesn't fit.

You'll need to exclude something large. I don't know what that's going to be, since only you know your data. But you'll use a copy script to do it - the User's Guide explains how in general.

It might be wise to get a 1TB SSD and put that into the system, then restore. Or now, given you know this isn't a very good Mac, to get a good one with an appropriately sized drive.

You can definitely migrate from a SuperDuper backup to a new Mac. Do it at first boot, as explained in this FAQ:
