However beware when up upgrade a pool as once you have you cant go back, and if you want the revert to your previous install you wont be able to. Therefore a general rule of thumb is unless you need a new feature on a new pool version dont upgrade it. A least wait a few weeks until your new install is fully bedded in and tested
