[Zope] Re: Trouble migrating from Zope 2.5.x to Zope 2.9.x

[Doug Morse]

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!
Doug
