The format and data in the file storage has stayed exactly the same for quite some time, so no migration is necessary. For 3.10 the index file format (data.fs.index) has changed, but this has happened transparently. ZODB 3.8 introduced experimental support for blobs (binary large objects), which have gotten stable and production ready with 3.9. There's no good documentation for them, but z3c.blobfile might serve as an example (http://svn.zope.org/z3c.blobfile/trunk/src/z3c/blobfile/). If you have any data that's bytes of 1mb or more each, you should investigate blobs. Not having to load all that data into the ZODB caches alone is really helpful, not to mention the various nice effects of having a smaller main file storage or the various supported backends for blobs. Apart from those, there's been a multitude of new config options listed in the changelogs (http://pypi.python.org/pypi/ZODB3/3.9.7#id14 and http://pypi.python.org/pypi/ZODB3/3.10.5#id10). It's hard to tell, if any of those would be helpful in your particular case.
