during battle, once damage is assigned but not yet applied can it be moved?

No. That effect is called "redirect" as you can see on Disciple of Khaine and .Warrior Priest

You can move damage only which is ON a unit, so it must be assigned first, and the unit must survive it. (or it will die before you could move the damage)
