[Migration] ConnectionStateError: Shouldn't load state for five.localsitemanager.registry.PersistentComponents

I am trying to migrate a Plone 4.3 installation with mixed AT and DX content to 5.1.2.

The Plone upgrade fails badly:

Any idea?

Got something similar:

The error means that a persistent object is used in a forbidden way:
i.e. via a foreign ZODB connection.

This typically happens when a persistent object is stored
in a global place (e.g. a module, a class or a global object)
or passed across thread boundaries.
In order to access a persistent object in those cases,
the object must be reloaded from the ZODB, typically via a new
ZODB connection.
