This video looks at some of the planning required for upgrading to Windows Server 2012 or Windows Server 2012 R2. Check out

In-Place Upgrade
An In-Place upgrade is when the upgrade is performed on an operating system and the upgrade process keeps all the settings, documents and applications. If the In-Place upgrade goes well, the computer should run much the same as the old computer, but be running a different operating system. It is important to check that when you purchase an upgrade that the operating system supports an in-place upgrade. In some cases, an upgrade is available from one operating system but an in-place upgrade is not. For example, an in-place upgrade is not available when the original operating system is running 32-bit and the upgrade version is 64-bit. When this occurs, you need to perform a clean install of Windows Server and then migrate the document and settings to the new install. The down side with an in-place upgrade is that any existing problems with the operating system are carried over to the new operating system.
In-Place Vs Migration
A migration is when the documents and settings are manually copied over and the applications are re-installed. Migration tools have existed in previous versions of Windows Server, however in Windows Server 2012 these migration tools have been improved. A migration also allows individual items to be migrated. For example, a single role can be migrated to any server. The advantage of a migration is that in some cases particular problems may be left behind and not migrated. For example, if the user profile on the server is causing performance problems on the server, migrating only the role to another server means the old profile is left behind and thus so is the problem.
In-Place Upgrade Not Supported
In order to perform an in-place upgrade you must be running the same architecture. Windows Server 2008 does not come in an Itanium or 32bit version so therefore no upgrade path is available. The version of Windows must be one that was released to manufacture and thus pre-releases, evaluations or preview editions are not supported. Also, it must be running the same interface, e.g. core or full. However the interface can be changed after the in-place upgrade. Also the upgrade must be in the same language. If you are upgrading to Windows Server 2012 you will need to be running Windows Server 2008 or above. If you are upgrading to Windows Server 2012 R2, you will need to be running Windows Server 2008 R2 or above.
