@@atct_migrator fails with reserved content ids ("security", "mail", ...)

[laulaz]

When migrating content, a traceback occurs if a content has "security" as id (migration works if the content is renamed before executing it) :

AttributeError: 'SecurityControlpanel' object has no attribute '__of__'

Same with "mail" content :

AttributeError: 'MailControlpanel' object has no attribute '__of__'

@laulaz have you solved the issue?
I think I had similar and it was conflict with plone.restapi adapters
If you uninstall plone.restapi during migration it could help but then after installing it again some links like /Plone/mail, /Plone/security might not be working

[laulaz]

@dest81 we didn't try to fix the bug, as concerned contents needed to be renamed anyway ... sorry
