I just used such a tool to migrate a client's data from one ZPatterns 
application into a new version of the application.

There are a couple of bugs I need to iron out to do with using minidom 
with very large racks.

The tool is not at all generic. It is specific to the data in my 
client's application. I'll be glad to post the code, but it is one of 
those crufty munging sorts of program. It is basically a couple of 
external methods. I suppose there are a couple of things to do with 
transactions, and minimising ZODB caches that might be useful to some 
people.

I've just got back from a long motorcycle trip... so I won't post it 
right now. I'll put the external methods somewhere nearly next week.
