Zope 3 is not backward-compatible to Zope 2.
You can not copy a Data.fs between them.

In general the migration path looks like:
1) Rewrite your app gradually using Zope 2.8, 2.9, 2.10 (when it comes
out) and gradually leverage more and more features of zope 3 via the
"Five" compatibility layer. (This is likely to be much harder if you
have significant dependencies on third-party code.)
3) export your data from zope 2 somehow, and re-import into zope 3. You
may have to write some of your own serialization code.
Step 2 is not well defined at this point in time :=)
