Hi we''re trying the new XCP 1.5 beta, we need to upgrade 3 pools with XCP 1.1 in the next weeks. At the moment, im trying to upgrade a test server from 1.1 to 1.5, but the installer told me that upgrade was not possible, and force me to a fresh install. When the 1.5 final will be out, wil be possible to upgrade from 1.1 without taking down the pools ? Thanks Marco
