Maybe, some of them. And it may not be easy.
For a long time, Zope supported two "BTree" packages,
the old "BTree" and the new "BTrees".
Starting with Zope 2.8, support for the old "BTree" package was dropped.
Zope 2.8 can no longer read "BTree" instances if you have
used them somewhere.
*If* this is your problem (your description so far does not
indicate it), then you need to make the conversion for
"BTree" to "BTrees" in your *old* instance, as Zope 2.8 (and above)
can no longer read "BTree" instances.
