Upgrade Guest OS to Windows Server 2012 R2 and use VHD from 2008 R2

I have a WS 2008R2 virtual machine (Host WS 2012R2) with two vhd/vhdx (Drive C: and D:). I want to upgrade this Guest OS to 2012 R2 by installing a new VM. Is it possible to create the new VM and just attach the Drive D: vhd/vhdx formatted on old 2008R2? What about NTFS issues? Will I be able to use 2012 R2 new features like deduplication on this Drive D:?

Thanks.
