Not those exact versions but similar ones, including from 2.1.6 to 2.3.x.  I
have gone through a series of upgrades, five or six in all.  At first I
simply backed up my data.fs file and used it to replace to new one put in by
the new version installation.  Lately, I have been exporting the whole
folder tree and importing that int0 the new installation at one shot, AFAIR.

Either way, I install the new Zope into a new directory.  Don't forget to
copy over any products you have installed, and any external methods. Make
sure you delete any *.pyc files in the external methods folder.   I haven't
had any problems.  Of course, make sure you keep a working copy of data.fs
just in case!

I'm not sure how well the export/import would work from 2.3+ to 2.4+,
though.  Some things get pickled for the export, and supposedly pickling is
not compatible between Python versions.  Anyone know for sure if that's
correct?

Cheers,
