Hello @trunky !

To continue your upgrade, you need to choose the "beta" value of the Update channel field in the Studio->Developer area (the Developer app can be installed for free) and save changes. The Upgrade button will appear, press it and upgrade the core and all installed modules step by step. As usual - backup your UNA files and database before the upgrade start. Requested your UNA studio details too because it's enough to have the stable upgrade channel between 13.1 and 14.
