Sorry, I should have included the detail that I've run multiple remodels after the move. Template bindings are removed, but the "components" are still there (disk, windows services, etc...) even though the devices are moved to "/Ping" device class. I'm planning to upgrade to Core 4 and then moving the devices to the new WMI windows device class. My concern is that there will be left over "artifacts" from the old device class.
Thanks!
