@mlevison exciting! Have fun setting up your new Mac!
I did a fresh install this year so I was in essence doing what you are doing - setting up a new device without the migration asssitant.
I followed these instructions: Moving DEVONthink 3 to a new computer - fresh install of everything - #5 by BLUEFROG It worked well and I added a comment at the time to report the little problems I had so that others could know exactly what worked and didn’t.
I actually followed Jim’s instructions for a couple of other apps I wanted to migrate with their data as well and that worked fine (I did it for Alfred and a couple of other apps that I can’t remember right now).
