I see. I don't know why the database seemed empty, but even after you fix that, assuming you're using Plone or similar, you're going to face a deeper problem: the catalog(s) in each site use absolute paths. To fix that, you will have to re-catalog everything in each site, which is probably the most expensive part of the ZEXP import. In other words, I suspect you won't actually save any time with this method of copying. Another possible solution is to shrink your template so that it's not so expensive to copy. If I have understood correctly, then this question is independent of the ZODB storage--you would have exactly the same problem with FileStorage or ZEO.
