In the menu click NMIS -> Export.
Select each device you wish to export (or click the checkbox in the right side of the table header to select all) and then click the Export button in the table header (right side).
If NMIS is installed on the same server your devices should be exported from Open-AudIT and should appear in NMIS. It may take a few minutes for the devices to be polled (NMIS has a 5 minute poll cycle).
If you don't have NMIS installed on the same machine as Open-AudIT, when you click Export you will be given a text file to download and copy to your NMIS server.
