I've moved my ISY 994i IR Pro (and PLM) to a new house, leaving behind all of my old Insteon devices.  What's the easiest way to delete everything from the ISY so I can start fresh with new devices & programs?  I was afraid if I reformatted the SD card that I wouldn't be able to connect to it any longer and wanted to ask beforehand.  Thanks!

Follow the factory reset instructions from the wiki.

Fantastic, thank you!  I just wasn't finding it on there but I didn't think to look for a factory reset.  I appreciate it!

@CJVann Your PLM also needs a factory reset.

You will also likely need the latest version of ISY you want to install after a factory reset.

If you left the older Insteon devices and they still can control themselves. I believe a remove PLM command goes out and removes the PLM addresses from all the module. So they are not trying to communicate wit a now gone PLM.

Great advice, all.  Thank you kindly.
