This topic is about Windows Server 2008 in-place upgrade to Windows Server 2012/2012R2. Article will be really short because there is no possibility to do in-place upgrade of Windows Server 2008 to Windows Server 2012/2012R2 when it has no Hyper-V role configured.
The only one supported in-place upgarde is possible when your Windows Server 2008 has Hyper-V role configured.
