[Zope] Database conversion

I am running Zope 2.10.5 I've just upgraded from Zope 2.7 I would like to move my database to the newly created instance. I followed the very reasonable and clear instructions here, http://svn.zope.org/*checkout*/Zope/trunk/doc/FAQ.txt (esentially, just moving the Data.fs file) However, the old data does not come up when I bring up the server again. Perhaps the old objects need conversion or some other juju? Any suggestions?
