Vista RC1-Restore Files from XP Backup?

I'm trying to migrate from XPsp2 (on one machine) to Vista RC1 on another. I
used the XP machine's Backup/Restore program to create a backup of
'everyone's' data files onto an external hard drive. When I plug the hard
drive into the Vista machine, Vista can see the backup file on the drive.
When I launch Vista's Backup and Restore Center, however, Vista cannot see
the XP's backup file. When I follow the link for "How do I restore files
from backups made using a previos version of Windows," it goes to a generic
Vista site. My searches of the knowledge base have been fruitless. My
searches of the Vista newsgroup reveal that several people have similar
problems, but I don't see any replies with definitive guidance.

So, how do I get my data files from XP to Vista RC1? Is there a 'good' KB
article? Has someone written something good on this topic already? I have
the original XP machine and files, still. I prefer to just bring in the
data, and not really the old XP settings, if possible. I'm willing to start
over, but need help with the approach.

(Likewise, I need to bring over my Outlook data files from the XP ruinning
OL2007 to Vista running OL2007, if there are any suggestsions on that.)
