Of course, you might be happy when you can import into a newer Zope version from an older one. At least, that makes some sense :-)
Of course we would be happy if we could do that. But export/import was never designed to deal with migration issue.
Export/import is essentially what the ZODB does all the time. If export/import does not work between given Zope versions, it is quite likely that the same Zope versions will have difficulties with storages exchange -- and this *IS* a migration issue, Zope should be concerned with (and not the applications). If it does, export/import will simply follow (in most cases). -- Dieter
