A little help upgrading old (but production) server

Hi all,

I am on FC2 and am following this 
http://linux.duke.edu/~skvidal/misc/fc2-fc3-update-with-yum.txt to use 
yum to upgrade to FC3. All goes well until

[root@example FC3]# rpm -Uvh fedora-release-3-8.i386.rpm
Preparing...                ########################################### 
[100%]
        file /etc/sysconfig/rhn/sources from install of 
fedora-release-3-8 conflicts with file from package up2date-4.3.19-1

I don't think I even need up2date but would prefer a clean update if 
possible. "yum update up2date" says no updates are available.
What can I do please?

Thanks
