Domain Controllers - same version and software?

Hi there, hope for some help here.

I am upgrading to Exchange 2013 and then 2013 SP1. The prerequisites for this when doing schema ext, etc is that the Domain Controller in the root domain that I am doing the extension and preparation from, has Windows Management Framework 3.0 installed before the 2013 preparation and Windows Management Framework 4.0 before the SP1 preparation.

My question is now, is it enough to install the framework packages on that specific domain controller? Or are there some rules or best practices from MS stating that all DC-s or at least all GC-s or all DCs holding operations master roles have to have the same version of this?

Thanks in advance for answering.
