Are you referring to the DesktopNow Management Database? I only ask as the post is in the LDMS area.

The Upgrade info is included in the DesktopNow Help available here:
Product Upgrade section:
Alternatively the Install and Configure Guide as a PDF (same content as Help) is available from our Product Documentation site:
Quick link here:
Hope that helps?
