Yes, do it after waivers. The system won't let you drop/add different years of the same player via waivers.
When swapping for another year of the same player, you drop the old year and pick up the new year with the same confirmation click, same as when swapping for another player. So, unless you drop him without picking his replacement (year), nobody else can take him.
