upgrading from repo format 1

I was a very early SVN user. I have a repo last timestamped January
2003 that I want to get files and data out of. When I run svn upgrade,
I get:

svnadmin: E165005: Expected repository format '3' or '5'; found format '1'

Do I need to install an intermediate version of SVN in order to
upgrade? If so, which version would you advise that I use?

Thanks,
Ben
