switching from ap flour to whole wheat ?

switching from ap flour to whole wheat ?

I have been baking a no kneed sourdough with 90% ap flour and 10% rye

 I want to switch this to ww and rye

 what do I need to do ?

 do I need to make a ww starter , or rye starter ?

 

 do I use the same weights as with the ap ?

do I proof and bake for the same time ?
