        You really shouldn't install RT4 into your RT3 source tree
        (/opt/rt3) and instead should be using make install to set up a
        clean environment. This will allow you to evaluate your local
        modifications and configuration changes as you migrate to 4.0.
        
        If you choose to force RT to install into /opt/rt3, or another
        existing RT 3.x install location, you will encounter issues
        because we removed the _Overlay files (such as
        Ticket_Overlay.pm) and relocated other files.  You will need to
        manually remove these files after the upgrade or RT will fail.
        After making a complete backup of your /opt/rt3 install, you
        might use a command like the following to remove the _Overlay
        files:
        
            find /opt/rt3/lib/ -type f -name '*_Overlay*' -delete
