Upgrading Samba to 2.2.2

[Robert Fultz - Lynn University]

   I'm new to Linux.  I'm looking for other directions and reasons NOT to
use Microsoft.  I setup my first RedHat - Linux Server and have been trying
to upgrade to Samba 2.2.2 from 2.0.7.  When it runs it says that there a lot
of conflicts with some of the files with the previous version of Samba
installed.  How do I get around this?  Can I uninstall the previous version
and then do a fresh install, HOW?
  
Thanx
