[Zope-CMF] Is there a way to change the meta-type of a number of object types

[seb bacon]

Because all your Documents are instances of a Document class, if your
Order class is different, you'll have to write a script to generate
new objects using the old data.  Something like

 for item in YourDocumentList:
   context.invokeFactory("Card", item.getId())
   context[item.getId()].edit(item.some_property, item.some_other_property)

That's a bit wrong, because you'll also want to get the correct folder
for the object rather than the current context, which you can get
using the getpath Catalog method...  

However, I'm not sure what you mean by 'Subject topics'.  If you've
just changed the metadata, but the actual instance is identical, you
can probably get away with changing the Type / meta_types of your
Document instances.  Not advisable though, if you subsequently change
the Card class.

Hopefully that points you in the right direction...
