[Koha] Koha Rebuild - Looking for the man behind the curtain

I'm installing a new Koha Server on Unbuntu o replace a dying server and I thought I could get some pointers here concerning the process. I have loaded Unbuntu 12.04 LTS Server and will be installing the Koha package on the server tomorrow. After I install the Koha package, I'm wanting to know how I can configure the Koha server to act like the one I'm replacing. Does anyone have any documentation on moving a Koha install to another server? Thanks for any help. Phillip
