This seems obvious, but want to make sure I am not missing anything. I decided to go from the Mac Mini M4 Pro with 24gb RAM (base model) to the Mac Mini M4 Pro with 48gb and the upgraded processor. It arrives today. My current on is only two weeks old.
- Time Machine backup in place already
- open new MM, plug it into monitors and restore from current backup
- swap back to old one, boot up and wipe device for return
- swap back to new one and off to the races
