Comprehensive path to globally changing an Ember application name

I built an Ember app with CLI and 2.0 – it was an app for hats made of plants, so I named it "plant-hat."

A few months later, I realized that people didn't really like wearing plants on their heads, so I retooled it to sell "Shoes filled with worms." I think this time it'll really take off.

So, I want to rename the app and any important parts of it - as if I built it as "shoes-with-worms" from the beginning.

What steps do I take so that I don't miss anything.
