How can I access an old ISY26 that was installed in 2007? This home has about 60 Insteon switches and plug-in modules and has been working great. The customer has sold his home and would like to disable the personalized programming. Is there a version of the Admin program that will still talk to the ISY26? Also, Can I upgrade the ISY26 to an ISY994i without loosing the link to all of the already installed modules?
