David,
I seem to recall from somewhere that using Data.fs was in some sense
more complete, or more supported, or more something from some old
migration guide, so I was shying away from doing an export/import. Also
there is the time involved in exporting/importing each site in the instance.
However, I gave it a try. When I did, I notice this text in 3.3.5:
Note: Zope can export/import objects in two dfferent formats: a binary
format (called ZEXP) and as XML. The ZEXP format is the officially
supported export/import format for moving data between identicial Zope
installations (it is not a migration tool). The XML export/import is
unsupported (and possibly broken under certain circumstances) - use it
at your own risk.
It is the it is not a migration tool part plus that identical is
underlined that worries me a bit. In any case, the import into an empty
4.0.0 failed in my case with:
Site Error
An error was encountered while publishing this resource.
Error Type: ImportError
Error Value: No module named LargePloneFolder
which I guess means (1) I have been using Plone too long :-) and (2) I
have to find and somehow try to get rid of LargePloneFolder objects
somehow before migrating??
Thanks for the tip, though, maybe it will work if I can figure out how
to proceed. Perhaps I will be able to get to Plone 4 one of these days
;-) I have be extremely strict about using any third-party add-ons,
just so migration would go smoothly. Looks like this time it is old
Plone stuff itself that it getting in the way. (BTW, we only use only
one add-on: PloneFormGen.)
I meant that we exported the database under Plone 3.x and reimported to
a new database in the same Zope instance (still Plone 3.x with the same
versions of all software). *Then* proceeded with a normal upgrade to
4.0 using the normal method and the new Data.fs.
