[Zope] No information about upgrading

Maybe this is too basic for you out there but there is no information in zope 2 distribution neither any of the docs on the zope site about upgrading from zope 1 to zope 2. At least somebody should say to not overwrite your zope 1 install with the zope 2 one (if you haven't tried, it doesn't work, thanks god I've got a backup) - Atentamente, Victor Perez Muena IS&T Support - Port Area (Los Vilos) Los Pelambres Project - Bechtel Chile Ltda.
