I spent several hours recently to import a .zexp of a Plone 2.0 site.
Got nowhere.

One suggestion I got (which I wasn't able to follow) was the
following.  If you have access to the original server, try this:

1) Make a full backup of the entire ZODB, eg. using repozo.py.
2) Set up a new Zope instance with all the same products installed,
using your new backup copy of the ZODB.
3) Go into the ZMI for this new instance, and delete everythign EXCEPT this
plone site.
4) Pack the database to get rid of all the other stuff.  Or make a new
clean backup.

There. You now have a Data.fs that contains only your Plone site.
Instead of importing the .zexp, just mount the database at the
appropriate path.

Disclaimer: I haven't tried this yet.
