How to keep history date before deleting a node

When you delete you lose the device data

You can save PDF some of what it has to monitor.
But pulling the base something of a node that there is more there's no way.

if you unmanage the node/interface the the data can be retained (still subject to your retention settings).

There is a idea request for a datawarehouse to hold this data so it can be held separately from the monitoring data.

Hi Richard, Could you please give a little more info for how to hold history data in data warehouse and how to see them in Solarwinds? Thank you.
