Setting up a new (or repurposed) Mac: 3 Manual migration – The Eclectic Light Company
Manual migration boils down to you copying, in the Finder, at the command line, or by running scripts, files from your old Mac to your new one. There is no single way to do this: you get to choose exactly what you migrate, and how you do it. I cannot, therefore, suggest any best way to do it. What I will do, though, is point out solutions to some of the pitfalls and problems which you may encounter.

Clone no more

One once-wonderful solution of migrating by cloning is almost certainly now doomed to fail. In this, you cloned your old Mac’s startup volume to become the startup volume for your new Mac. This was usually performed using an external disk as an intermediary, with software such as Carbon Copy Cloner or SuperDuper.

Archiving cryptographic secrets on paper — whitequark’s lab notebook
"In this note I show a script for splitting small amounts of data across multiple barcodes and generating a printable document. Specifically, this script is limited to less than 7650 alphanumeric characters, such as from the Base-64 alphabet. It can be used for archiving Tarsnap keys, GPG keys, SSH keys, etc."
