Why is a Polisy unavailable for purchase? I am interested in getting one but both models are out-of-stock and have been for a while.

Thanks for the advice. Now I know that new ISY994i's ship with R5 that rules out the testbed approach. I guess I just have to go with the upgrade path. I really want to get to R5 with all it offers. Also saves me getting another ISY.

I have been watching the progress of Release 5 for a long time. I now have the time to do it. I realize this is a big upgrade and the release is not yet official but it is now an RC, not Beta. I have 2 homes both running an ISY994i on 4.7.3 and have been with UD since they started - I helped debug the ISY26 back in 2007! I am cautious of the R5 upgrade so am considering buying an extra ISY994i and using that as a test bed. All controlled devices are Insteon although I do use X10 to trigger my Ademco alarm system. I have the weather module on one ISY441i. I assume that shipping ISY994i's come with 4.7.3 on them, so I would just restore my backup to that, replace the current one with it and start the upgrade. Is there an impact on my Insteon devices that will prevent me from reinstalling the original ISY994i if the upgrade fails? is there a residual network effect on Insteon devices? My approach would be to swap the ISY's in & out until I am happy with the release 5 one. The I leave it in and move on to the next house. Thanks
