Did you know that you do not need to do this? You could have created
repositories with SVN 1.0 and still serve them with 1.4 as well as the
upcoming 1.5. I think there have been two releases where there were
some minor improvements you could get by doing a dump/load, but you
have never had to. The next release will add small a SQLite database
to the repository, as an example, and it will just get created the
first time it is needed.
