Yes, using the export/import mechanism.

Another option is to mount both ZODB's and then copy the objects.

It is necessary to decouple the copy from its source before
it can be stored in the target. Apparently, copy.deepcopy is
able to reliably decouple.

Stupid question: Which one? I tried straight xmlpickle and got some errors 
randomly.

I was referring to the binary export/import, which is the only one  
supported by ZODB, afaik, although it's been a very long time since I  
looked at that code.

ZODB/ExportImport.py

This defines a class that gets mixed into ZODB.Connection.Connection.
