Should Ntfrs service be disabled on Windows 2012 Domain Controller

I have added a new Windows 2012 R2 Domain controller to an existing domain.  The existing domain controllers are running Windows 2003 and will be decommissioned at a future date.  Currently our domain functional level is at Windows Server 2003.  After adding the Windows 2012 R2 DC to the domain and running dcdiag on it to check for issues the following was reported back:

      Starting test: Services
            Invalid service startup type: NtFrs on DC1, current value
            DISABLED, expected value AUTO_START
            NtFrs Service is stopped on [DC1]

So currently the File Replication Service (NtFrs) is disabled on the 2012 DC.  According to the above it looks like the NtFrs service should be changed to Automatic - Is that correct?

As far as I can tell SYSVOL replication is functioning properly:
      Starting test: SysVolCheck
         ......................... DC1 passed test SysVolCheck

I see this in the event log "The File Replication Service has enabled replication from OLDDC to DC1 for c:\windows\sysvol\domain after repeated retries."
