It is.

You need to upgrade the versions on the Windows platform to match those
on Debian - not just Plone and Zope but also their 3rd party products -
for a .zexp import to work.

If you cannot do this (I suspect that you may the person who asked a few
days ago on the Plone list?) then I am sure that you will not be able to
use the .zexp import method - unless there is some magic in the world of
which I am unaware, this will only work if you have /exactly/ the same
versions. I'm 99.99% certain that is a waste of time.

You you /might/ be able to do something either with the XML import
method or by moving or mounting data.fs, but I very much doubt it, and
very much doubt that the time spent would reap any reward. I'm 99.9%
certain that is a waste of time.

If the sites are /very/ simple, you might be able to create an empty
site on Windows and move content objects using WebDAV (or other methods
in the case of user folders).

You have a problem, in that you are trying to "go backwards" in terms of
the Zope version, and if it is not impossible (which I think it is) then
the solution is going to be at best labour intensive, at worst
unreliable - probably both. Even if it's possible I would advise against
it as there is no way of evaluating the reliability issues (I think you
are in a minority of one here).

I would expect that you would have to accept that the Zope version, at
least would have to be maintained, and I would run a separate Zope
instance at this version in parallel to the existing instance on your
Windows server until you /can/ upgrade the primary instance - not the
solution you want, but possible and without the kind of reliability
nightmares you may run into if you do succeed in moving to a prior Zope
version.
