Hi Jonathan, Ah, great point -- I hadn't thought about that re: mounting the old Data.fs root vs. non-root. I'll give that a try right away -- that could be a quick and simple fix. Great thinking! One thing I can say right off is that this difference (i.e., root-mounted vs. non-root-mounted) did *not* matter when migrating from one Zope 2.9 installation to another Zope 2.9 installation. That was something I've had to do along the way here and worked without a hitch. Let's see what happen, though. I'll try it later today and report back. Thanks again!

Hi Maurits,
Thanks for the speedy reply!
Hmmm... you make a good point about the ZODB file size. At installation, though, there was a notable difference. The new, default Data.fs was 2.9MB, whereas the mounted, older Data.fs (renamed, of course) was/is 4.4MB.
I like your suggestion re: just upgrading though each minor release number. If someone doesn't suggest an alternative, speedier route, then I'll do as you suggest.
I would try the following:
1) Create a new, clean 2.9.x installation 2) Copy the Data.fs file (your 2.5.x version)
And see if it works. It could be that your non-root installation is messing things up. If you have any ZCatalogs you will need to fix up the indexes (see the READMEs, there was some change in 2.6? 2.8? that requires a utility to update the indexes).
