Your middle option is best, especially since you're changing OS here
too. Shut down svnserve (just to make sure no one commits after you've
started your migration - that won't be a deal-breaker but it adds some
extra work you'll have to do), then run svnadmin dump to get a
portable representation of the repository. Install the latest
Subversion on the Linux box, create the repository, then svnadmin load
to import your repository. As usual, the fine manual provides:
http://svnbook.red-bean.com/nightly/en/svn.reposadmin.maint.html#svn.reposadmin.maint.migrate

By doing this, you'll keep your data safe *and* take advantage of the
many improvements made to Subversion and the back-end storage over the
years since 1.3 was released.

You'll also want to look over the Release Notes as they have some
information on upgrading as well.
