I just did a test upgrade from WUG 8.0.3.  Maps imported just fine, thanks for adding that feature in SP1 of WUP2005.

All of my devices in WUG803 were resolved by hostnames/dns.  A few of them, after being migrated to WUP2005, were unable to resolve to the correct IP address using the hostname/dns polling method.  Through the application on the server, I tried to go into the objects in WUP2005 and changed from the hostname to the FQDN.  Each time I did that, I got an error that I was providing an invalid address.  However, if I used the WEB interface and changed the polling method and changed it to hostname/dns, it worked just fine.

Very strange.
