Very basic question regarding baking details

Hello, let´s say I make a low poly model and make another model where I add high poly details, I make a normal map of the high poly model. Which model do I unwrap for texturing and making an AO map?

 

Theres a few methods what i do is this:
Non-organic (guns etc) make the low poly unwrap it then make the high poly then bake the normal map, AO make texture.

Organic(human) i usualy sculpt the high poly then retopologise and bake/project the details to the retopologised one which i had unwrapped.

 

okay, but on the non-organic one do I texture the low poly and do I make a AO map of the low poly or do both those things on the high poly?

 

It depends on what you want your pipline to be.

for me id create the low poly unwrap then duplicate that model create the high poly then bake the normals using a cage then texture the low poly and then bake the AO from the normal map you can bake from the mesh i think you can use a cage to do that but ive never really done it that way.
