Thanks for the suggestions. I'm not sure if I've done the "audit"
correctly, but having gone into a few random articles via the plone site
itself, as well as doing a "find" via the ZMI for objects of type
"SimpleForum:Forum" or "SimpleForum:Post" I didn't come up with any left
over bits of SimpleForum.
I also wasn't sure about how to go about doing the full catalog rebuild,
but what I did was go to the plone instance's "portal_catalog", put a
tick in all the items in the "indexes" tab and pressed "Reindex".
I then did a pack, shut down plone and copied Data.fs to a fresh install
of zope/plone on the new server.
Unfortunately the results are exactly the same:
Result of the attempt...

I'd be grateful for any other suggestions that might help me upgrade
this plone instance. Is it possible, for example, to find out what
object(s) the upgrade is failing on, and excising it from the database?
