just that you also need 24v everything
hotend heaters (can get away with pwm limit to 1/4 power, but not recomended)
heated beds, 24v need
and fans! 12v fans tends to burn out at 24v.
Steppers are fine. Pololu modules are fine.
Controller is fine, designed for it.
If you have any high tech endstops, such as inductive sensors, power to them will need checking.
