Restoring Lotus Domino Server 7

Our Lotus notes administrator quit. The server thats working now is dying. Before I got hired the old admin purchased a new server and was in the process of moving the old server ID and database to the new server.
My question is whats an easy way to move the data over and get this machine going so I can down the old one. I told the company when I got hired I worked with Lotus Notes 8 years ago and have not touched it since. I got moved off my original project to take over this one. Someone please point me in the right direction.
