Yeah that was my first reaction when I saw the title, "How hard is it going to be this time?" since it took me 2 days to migrate to the v4 last time.

  Why upgrade?

    Because if you don't upgrade, you are stuck with whatever version of React created at the time. You don't get stability & performance improvements, bug fixes, you can't potentially install some newer libraries requiring the new version. Not keeping up with upgrades is making the code rot slowly.

    Because sooner of later you'll have to. Upgrading frequently minimizes the delta.
