Overview:
This article provides guidance to migrate a File server running Windows Server® 2003, Windows Server 2003 R2, Windows Server 2008, or Windows Server 2008 R2 operating systems to a server running the Windows Server 2012 operating system with the File server Services role installed. This includes cross-architecture and stand-alone migrations, as well as configurations for a server in a cluster.
Scope: Currently all 2003 OS for windows servers are EOL by mid of 2015. We would need to upgrade all the Windows 2003 to Windows 2008 / 2012 and file servers also having windows 2003 OS which needs to be migrated from windows 2003 to windows 2008 / 2012.
Supporting Migration Scenarios
This guide provides instructions for migrating an existing server that is running File and Storage Services to a server that is running Windows Server 2012 R2 or Windows Server 2012. This guide does not contain instructions for migration when the source server is running multiple roles. If your server is running multiple roles, it is recommended that you design a custom migration procedure for your server environment, based on the information that is provided in other server role migration guides. Migration guides for additional roles are available on the Windows Server
