If you are on AOSP or you do not have trebuchet installed, I would say you could go without a wipe. If you are on CM9. Then (you can try) without a data wipe, but I would do one if it doesn't work.
Google Galaxy Nexus running Purity 4.3.0 or Kitkat! (Whichever one I feel like using :P)
Did I make your day? Do you want to make mine?
