[Setup] Problem upgrading from 2.14 to 2.53: KeyError: _Real

I have tried repeatedly to upgrade a Plone site (2.14, Zope 2.87, Python 2.35,
Windows XP) to Plone 2.52 or 2.53 running in a completely separate Zope
installation, by dropping in Data.fs.

After migration attempt I get the error KeyError: '_real' (see traceback below).
It also appears in the ZMI left-hand column!

Do I need to "clean" the Data.fs somehow? 

Thanks for any help.
