I'm trying to upgrade to Plone 5.0.5 an existing Plone 4.3.10 website and after running successfully buildout with the new versions.cfg I have
bin/instance fg saying that all is ok.
Then I have two
AttributeError: type object X has no attribute '__iro__' with both IActionIconsTool and ITinyMCE. Adding Products.CMFActionIcons and Products.TinyMCE then makes it fail with a ZCML conflict due to having plone.app.controlpanel...
I'm sort of surprised to have this issue and I'm not seeing many problems on migrations related to that... should I remove those IActionIconsTool and ITinyMCE before migrating? Should p.a.upgrade handle that?
