Over at the Concentrated Technology blog this morning I post a how-to summarization of the process you need to complete to migrate your domain from FRS (ick!) to DFS-R (yea!).

A little backgrounder before the jump: Just like with the previous versions of Windows Server, the domain migration process requires all DCs to be upgraded to the new OS version before you can upgrade the Domain Functional Level. Once all DCs are upgraded, navigate to Active Directory Domains and Trusts, right-click the domain, and select Raise Domain Functional Level.

Once you complete this step you'll begin enjoying the benefits of the upgraded domain. What's interesting, however, about the FRS -> DFS-R changeover is that upgrading the Domain Functional Level only enables DFS-R for use. It doesn't directly complete the conversion for you. In order to complete the conversion, you'll need to complete a few additional steps using the DFSRmig.exe utility.
