My Zope 2.10 server tells me: Note: Zope can export/import objects in two dfferent formats: a binary format (called ZEXP) and as XML. The ZEXP format is the officially supported export/import format for moving data between identicial Zope installations (it is not a migration tool). The XML export/import is unsupported (and possibly broken under certain circumstances) - use it at your own risk. I am moving a Web app from Zope 2.7 to 2.10. I exported it from 2.7 and imported to 2.10 and this worked. But then I saw the above note. Is there a migration tool? Where is it, please?
