what are you missing...? You do not paint a very big picture.

What older Mac, what older macOS— what new Mac, what new macOS?

The most trouble free way to move to a new machine, is using the Setup Assistant on the initial boot of a brand new machine— you have one shot here. Set up your MacBook Pro - Apple Support

The second best way is use the Migration Assistant.

Migration Assistant doe not MOVE anything.

It creates a COPY on the new computer, of the items you selected.
