How do you put an enchanted item or an enchanted potion in an item frame with command block?

Question

All I have is this, also how do you replace it so the old frame and item doesn't go flying into the air from 2 items occupying same space.  Thanks in advance!

/summon ItemFrame x y z {TileX:x,TileY:y,TileZ:z,Direction:0,Item:{id:(Your Enchanted Item or Potion),Count:0},ItemRotation:0}
