Formula to cows milk and food

How do you transition a 1 year old from bottles of formula to cows milk and actual meals?

My baby is almost 11 months and does 5 bottles a day, and small meals of breakfast, lunch and dinner (mostly purées because she has sensory issues and doesn’t like certain textures)

Everything I’ve read makes it seem like the day they turn 1, they’re cut off from bottles and formula and it’s straight to sippy cups and milk.

Can someone explain how to do a smooth transition from one to the other?
