I have a site (several, actually) in 6.0.14 that is failing to upgrade properly. The @@plone-upgrade page gives a warning about packages that have been installed at one point but are no longer present. I believe this is a false positive, those were installed and then uninstalled awhile ago. I am including it here for completeness. The upgrade otherwise performs without error.
However when I load a page I get a 500 on every resource request and the WSGI client outputs this many times:
ModuleNotFoundError: No module named 'Products.CMFPlone.PropertiesTool'

I know this upgrade removes the portal_properties object and I can see it's gone. But some object in the ZODB is still referencing it?
edit: running zodbverify (can/should I delete these objects?)
