WordPress MU

I need to go from 1.2 to the latest version. Reading the forums, I understand it is best to go sequentially. So I am looking for the older versions.

Where do I download them? I cannot find them anywhere.

Thanks!
Chris

Never Mind. I just saw a new post and they showed me the link to the Trac.

However, at 1.2.5 what versions do I need to jump to?
1.2.5 => 1.3.3 => 1.5.1 => 2.6.1????

Do I just take the most recent for each step?

Yep.
