The FSFS part is portable, that is, the stuff living in repos/db/.
So is everything else, *except* possibly the contents of the dav/
directory.

If you are using mod_dav_svn, then as I mentioned before, it uses the
apr_dbm_*() API to track the names of transactions ("activities", in
dav parlance). The exact dbm being used may vary from system to
system, and the resulting files aren't guaranteed to be portable at
all. (For example, if it turns out that BDB is being used, then BDB
is *definitely* portable between different endian-architectures.)

The thing is, the 'activities' database is just a bunch of transient
temporary data. Once a commit completes, the activity is removed
from the database (or if it isn't, it doesn't matter; the activity
is never looked up again.) They only persist during a commit. After
that, svn clients forget about them forever. So the simple answer
is: forget about them. If you're copying the whole repository to
another machine, just delete the contents of repos/dav/. A new
database will be automatically recreated by mod_dav_svn the next time
a commit happens.
