You will have to have or make an access hole in the wall on both ends of the copper pipe to cut it loose and pull it up {or down} out of the wall. When you pull it - tie a heavy wire or cable to it to tie to your plastic pipe to pull back through the wall. If it passes through stud braces it can get hairy and you may have to cut a hole there also to feed it through the stud. After you replace and hookup the plastic pipes you have to repair the walls.
