Upgrading subversion

I have installed subversion 1.0.1 on Windows XP and used the Apache based
server.
Now I want to upgrade to version 1.0.2.
How can I do it without having to de-install and install subversion again?
Can I unzip the files to the same directory where I've installed
subversion?

Thanks
