I think the attribute error on data is just a symptom of the BTree
failure. The object has no data attribute, because ZODB failed to
unpickle the object that would be assigned to data.
I don't know what happened with backwards compatibility for the old
BTree classes. When Jim and

I don't know if there is any documentation for BTree,
I don't know of any dcos for (the old) BTree either.
so the code will need to be your guide. I checked the code and each of
the BTree types does support items(). So walk over the database, find

Hmmm... I suppose you could write the script in Zope 2.7 and tell people
they have to use that version of Zope to convert the database before
upgrading.

I announced that, for now, The Zope head won't work with old databases.
We are going to have to come up with some code to deal with the
old btrees and intsets.
The good news is that, databases created with Zope 2.7 final should
work. :)

The default Zope setup has two databases: the main database and the
session database. So it's not completely nonsensical for any
default-configured Zope to raise the error (although I have no idea how
this error is occurring). It might be worthwhile to specify a main
database explicitly in
