Here's the scenario. There's a currently working Gentoo server. It's in charge of user accounts, website, email, and other things such as CVS and SVN repositories. I have a new Fedora 9 computer that I want to use as the server. So I have to transition everything over to the new computer and set it up as the server.

My idea is to first set up the servers. I will follow the articles posted for this. Then I will copy all of the data from the Gentoo computer to the Fedora computer. How can I move all of this data over to the new server? Which files do I copy? For example, the users have past emails they are saving. How do I preserve this data?
