Moving TFS 2010 application to another server

I have a TFS 2010 application installed on server1. I have the data tier on server2. We are going to get rid of the server1. I want to install the TFS application on Server2 开发者_如何学Go(same server as data tier). First of all, which configuration option do I pick during the install? Do I have to bring my server1 down before installing application on the data tier server2?
