将 Plone 4.1 + Dexterity 站点迁移到 Plone 4.3 站点后，/manage_workspace 变得无法访问。无法执行数据库迁移。

ZMI 根目录仍然可以访问。

AttributeError: type object 'IIntIds' has no attribute '__iro__'

也是@@plone-upgrade无法访问的。

需要任何想法或特殊迁移吗？

在 Dexterity 2 中，默认不再安装关系字段支持（包括安装 intids 目录）。要获得它，您需要使用 [relations] 额外安装 Dexterity：

[instance]
eggs =
    plone.app.dexterity [relations]

这记录在http://plone.org/documentation/manual/upgrade-guide/version/upgrading-plone-4.2-to-4.3/dexterity-optional-extras和 Dexterity 发行说明中。
