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).
