Has anyone migrated from the original z-wave dongle to the new one? Release 5 does not support the old dongle. I decided that replacing the dongle in my 8 year old ISY was too risky, so I bought a second ISY with the new dongle already installed. I am finding it difficult to migrate, which probably means I am overcomplicating things, so I'm hoping someon can help. The new ISY shipped with 5.3.0. I restored my old ISY to it and then upgraded it to 5.3.4. I have 11 z-wave devices. I then restored z-wave and only 8 of them showed up. Of the 8 that I can see on the ISY list, five are labled "Unavailable" and nothing I have tried from the z-wave tools menu has changed that. What should I do now? The only opton I can think of is to relink the 8 devices that are not currently working, but that seems like a lot of work, given that the process I've tried to follow by backing up the z-wave dongle on my old system and (eventually) restoring it to the new one should avoid that.
