Rearranging archive

I have inherited an archive that was created without using the
recommended directory structure hosted on a Windows XP box set up with
Apache and SSL. Everything works fine except our project is now to the
point where I want to start using tags. Since the archives were created
without a 'trunk' I don't have a good way to do this. What I would like
to do is fix the archive so that the directory structure looks like the
recommended. I have not been able to find a way to move the entire
repository into a new directory tree so that the code files are in a
'trunk' directory.

What I have now is:
archive
    proj1
        project files
    proj2
        project files
etc.

What I want to move to is:
new archive
    proj1
        trunk
            project files
        tags
        branches
    proj2
        trunk
            project files
        tags
        branches
etc.

I'm sure I'm trying to make this harder than it actually is but so far
I'm striking out.
