Hi all

I just played around with mirating just some of the content at once and could migrate FileBlobs, ImageBlobs and Topic.

With Documents and Folders I have some problems. When I try to migrate the Documents, I get the following error:

Traceback (innermost last):

Also here: How can I find out, what the problem with this Document is? When I open it in Plone, I cannot see anything being wrong :frowning:
-> I need to migrate over 350 Documents and 33 Folders...

Than kyou for your help and kind regards
