Create a bootable ISO image based on current server setup

I have a server now that runs our CRM, vTiger. It has been HIGHLY customized and I would like to be able to recreate our system with all the modifications from a bootable DVD. I want to create a bootable ISO DVD so that if I ever had to, I could just install it from DVD on a new system and everything that is currently on my server be duplicated on this new system. I do have a mysql on the server, which is massive.. I dont care so much about bringing the database to the DVD, it can be setup with a blank database, but still needs to have all the config files there, etc... email me with questions..
