2012 R2 RODC in Windows Server 2003 environment

Hi,

Is it possible to introduce a Windows Server 2012 R2 RODC into a Windows Server 2003 environment? All DCs are Windows Server 2003 R2 SP2 and the FFL and DFL are 2003.

I know it is possible to prepare the 2003 forest/domain, introduce a Windows Server 2008 R2 writable DC and then install an RODC.

My question is can this process apply to server 2012 R2?

So can I prepare the 2003 Schema Master with the 2012 R2 ADPREP command, install a writable 2012 R2 DC and then a 2012 R2 RODC?

Im guessing its possible but would it be supported?

Any help is appreciated.
