Being able to put a device in a decommissioned state for historical purposes.

Hi All

I would like to have a proper way to decommission a device in Solarwinds NPM and sub modules in order to keep histoircal data.

Ie

At the moment when  I want to decommission a device:

• Keep the device in a decommissioned state so I can see historical CPU usage, and config files

At the moment I have achieved this by changing the IP to a non routed IP and put it in an "unmanaged state" for 10 years in the future. to me though this is a bit of an ugly way to do it, as I need to keep historical information, and I will need to do the above for devices that have been replaced with new hardware as well.
