unRAID 5.0 has now been officially released. Considering the significant changes, upgrade is not as smooth as it used to be so it is better to start off from scratch with a clean USB drive that only contains disk configuration. With the new add-ons management options it requires less tweaking in the ‘go’ startup file. Please read the release note. Depending of your current version you might just have to upgrade the unRaid image while with other (i.e. any 5.0 beta) it is advised to go through a fresh installation while using exisiting disk configuration.
