Hi vlsi99x,

You can go to Control Panel > Uninstall a Program. Select Norton 360 2.5 and click Uninstall. This will backup the settings of Norton 360. Then restart the computer and install NIS 2009, which will import the settings. I am not sure about the network map settings, but this is the routine to get most of the settings like Identity Safe, AntiSpam Blocked/Allowed list etc.
