Given a holomorphic self-map $\varphi$ of the ball of $\mathbb{C}^N$, we
study whether there exists a map $\sigma$ and a linear fractional
transformation $A$ such that $\sigma\circ\varphi=A\circ\sigma$.
This is an important result when $N=1$ with a great number of
applications. We extend this result to the multi-dimensional
setting for a large class of maps. Applications to commuting
holomorphic self-maps are given.
