I have bought a Virtual Private Server, and has apache, PHP

Hi,

I have bought a Virtual Private Server, and has apache, PHP and MySQL (with user and pass) set up.
I have tried to find some guides online, on how to move a Wordpress multisite installation, but i can't find anything there is easy to start with.
I also have the mod_rewrite set up correct.

How do I move my whole multisite now, and point my domain to the new server?
