You can create a new account using MyHarmony and copy the settings from the Logitech Harmony Remote Software account, but you cannot access the older account directly. These remotes are supported by both the MyHarmony desktop software (recommended) and Logitech Harmony Remote Software 7.x however, any accounts originally set up using Logitech Harmony Remote Software 7.x cannot be accessed using the MyHarmony desktop software.
