For each Aranet PRO base station it is possible to register the base only ONCE to an Aranet Cloud organization with a FREE TRIAL license. If the user wants to change the registration of the Aranet PRO base station that has been already registered to an organization with a FREE TRIAL license, then the user can register it again only to an organization with a paid license. There is no limitation on base station registration change between 2 organizations with paid licenses.
