Now we are at least two of us. ;-)
Last week I've done nearly the same:

What version of CMF?  I've CMF-1.3 and ran into the problem, that 
a method from CMF changed its API from CMF-1.2 to CMF-1.3.  
Instead of going back to CMF-1.2 I hacked and applied a patch
to migrate_content and wrote the following EMail:

Hi Jean-Paul Smets,

yesterday I stumbled over your exciting work (the Base18 product for Zope)
and downloaded it to play around with it.  

I've tried it here on my notebook together with Zope-2.5.1 and CMF-1.3beta1.

Due to this I noticed a API change in CMF which affects the operation of
    erp5/Base18/Extensions/MigrateContent.py
The API of the method manage_addTypeInformation() of the class TypesTool 
has changed between CMF-1.2 and CMF-1.3: This method now has another 
formal parameter called 'add_meta_type', which (as far as my very limited 
understanding of CMF goes :-( ) should be 'FactoryTypeInformation.meta_type' 
from CMFCore/TypesTool.py itself.  Don't ask me why.  

To get around my problem I hacked the following patch into 'Base18'.
Please have a look at it:

With this patch the external method 'migrate_content' works successfully.

Hope this helps.
