I've upgraded to v9 and it imported all my monitors. It created a device for every monitor, which was pretty helpful. The problem I have now, though, is that I want to move monitors from one device to another, as I don't need 1500 devices. For instance, I have a router with 400+ T1s attached to it. Each one of those v8 monitors had a v9 device created. I need to move all of those devices' monitors to my main router device.
I've tried several different methods and none will work, including moving monitors to the Orphaned Monitors group. My next step is to export all my monitors, delete them all, then re-add them back in without parent IDs.
While I did spend a few months testing the beta version, this particular scenario did not present itself, as I had assumed all the monitors would be imported as Orphaned Monitors and I could just associate them to devices from there.
