I wouldn't try using export / import to move between versions of Zope
(even versions closer in time than 5 years! ;).  Instead, I would copy
the Data.fs and move the copy into the instance home of the new version.
In fact, I would probably migrate across each separate "major" revision:
 bring the copy up under 2.3.3, with the versions of your local products
(if any) which were current when that version was released, then do the
same with 2.4.4, 2.5.1, 2.6.4, 2.7.9. 2.8.9, and finally 2.9.7.
