[Zope] Copying a Zope Site

Hi everyone Currently I am using the RPM version of ZOPE(2.2.2) from Jeff Rush. I have installed the current verion 2.2.4 non RPM version. I want to transfer my files from websites & products from the current site to the new install. Which files and directories do I copy?. The RPM versions create a lot of directories and a startup file. How can I use this startup file on the new server? Thanks in advance. Mohan.
