If the plant is not actively growing new roots to pick up where the old ones are leaving off, there can be issues, as the old roots are just not able to keep up with the needs of the plant.
Two things to consider about that though: 1) the degree of difference between the root zone environments controls the severity of the change, and 2) very often, going from the old to the new version of the same medium is an improvement - the old roots grew into that medium when it was fresh, so will be in better shape to accept "fresh again" upon the change.
