We have a Small Business Server 2003. We just purchased a Dell Server SBS 2011. I assume it is going to come pre loaded with the OS. I have been reviewing the migration process and have a question. There is a step that calls for the installation of Windows SBS 2011 Standard in Migration Mode. I haven't turned on the server yet, should I bother running through the initial setup and connecting it to the domain? Or can I skip this part and used the pre installed OS by Dell.
