title: RPM upgrade uninstalls the RPM
body: <p>I am upgrading our project RPM.  The problem is when I upgrade from projectname-1.0-0 to projectname-1.0-1, it first installs the new project and uninstalls the old project, which, in overall view, removes my project entirely.  I have used "vv" option while upgrading and the output showed the uninstallation is done after installation.</p>
  
  <p>Somebody please help with this problem.  Is there anything I should change specifically in the RPM spec or rpmbuild options?</p>
