I'm not sure that this is possible but we have done a big network discovery and imported all the nodes into the netperfmon database.
What we would like to do is keep this polling and collecting data whilst working on anther npm instance with a new database and import nodes a subnet at a time?
I guess that we can only have one instance of NPM with one database at a time so I think
we would have to delete the old database and start from scratch?
Any advice would be greatly appreciated
