You cant move a special effect, the best way to simulate it is to either
A. Create a new unit in the object editor, and change its model to the special effect your trying to create. This is great if you want to scale the special effect to make it bigger/smaller.
B. Create a dummy unit, and add a special effect to the target, and move the dummy unit.
Either way, your limited by a units max movement speed of 512. To get around this, you need to move the unit using a timer, and moving the units position every .3 seconds toward its destination.
