I am now in the situation were I have a device that is failing for an unknown reason, does there exists any documentation that explains the steps that are needed to replace the device?
I see this option in the GUI but can't seam to find out what is needs to be done from the Device and Hub perspective.
I have used it successfully.
If memory serves me I first made sure the new device was excluded by putting the hub in exclude mode and putting the new device in exclude mode.
When excluded I then hit the replace button for the device I wanted to replace and then put the new device in include mode.
I'm not sure if it worked first time or not but I definitely got it to work.
Good luck.
