How to Convert a Drum Brakes to Disc Brakes?

Hey there i am new here :) I got an Nissan micra k13 from 2013.
Jeg overvejede at skifte mine bagbremser fra tromlebremser til bremseskiver.
I was considering changing my rear brakes from drum brakes to discsbrakes .
Have anyone tried it before? if yes what did you use? and where did you buy the Disc brake conversion kit?
I work in a Nissan dealership and am keeping my eyes open for parts that I could transfer over, If i find anything I'll let u know.
