Transition to non-breast milk

I’m trying to be prepared for my child to transition to dairy milk from breast milk. I have a great freezer stash, I bought the dr browns straw bottles for now, and my plan was to slowly increase the dairy milk and decrease the breast milk until he will drink straight dairy milk. I’ve heard that once he turns 1, it’s best to switch from milk as a meal, to milk with a meal, I’m just not sure how to accomplish that without it being abrupt? Does anyone have any advice or pointers on how they went through this transition?
