Removal - exacto knife, razor blade and patience. I put a thin bead of black acrylic adhesive on top of the old when I replaced it as an extra precaution and used a hairdryer to thoroughly heat the existing adhesive after getting it back on.

A tug test after it cooled down indicated good adhesion all around and I am confident the seal is re-established. Heavy rains last night and no moisture or wetness. Also made sure the weep / drain holes were clean while I had the barrier off of the door.

I picked up a new vapor barrier just in case... which I can/will return for full credit since I didn't damage the old one. They now sell a double-sided tape for applying a new vapor barrier as well if you aren't comfortable working with acrylic adhesive.
