And make damn sure you've got clean backups *before* and immediately *after*
the migration.

In fact, strongly consider this as a good time to do cleanups: making sure
that you do a "svn switch" for clients and have a new hostname for the new
server will help you enforce this. And this is a good time to switch to
FSFS.

Also, consider using "hot-backup.py" in order to get all the hook scripts
and permission files, and to make clean backups before the move.
