As it has been said many times, you cant keep Discus with Angelfish because the Angelfish harbour an internal parasite that effects Discus but not the Angels.
What I would like to know is, if you have kept Angelfish in the main tank for many years and move them to another tank, would you be able to keep Discus in the Main tank afterwards, without giving it a complete clean out?
