A 4.4 MB Data.fs *is* rather empty. That is only marginally bigger than the size you get when you start with a fresh zope instance. Are you sure the objects you expect are actually there when you start a 2.5 Zope with this database? > I'm wondering if there's some sort of "upgrading" of the ZODB file I need to > perform?

Not sure, but you might need to first upgrade to 2.6, then 2.7, then 2.8, then 2.9. At least I would not be surprised if that is the case. > Just for completeness: The only thing different about the new Zope > installation is that the old Data.fs file is being mounted within Zope under > a subdirectory (e.g., "/sitename") instead of the root directory (i.e., > "/").

I would first migrate the 2.5 database to 2.9 in a separate zope instance with only this database, not any others. After that you can try mounting that migrated database together with the others. This is just a guess though: I have never tried anything like this. -- Maurits van Rees | http://maurits.vanrees.org/ [NL] Work | http://zestsoftware.nl/ "Do not worry about your difficulties in computers, I can assure you mine are still greater." _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
