What I am trying to do is transition our domain from Server 2003 Enterprise x32 to Server 2008 R2 Enterprise x64. Here is what I have done thus far. The 2003 server is a physical machine, the 2008 server is a virtual machine.
Built a virtual machine that has Server 2008 R2 Enterprise x64 and joined it to the domain as a domain member. On the 2003 DC, Raised Domain Functional Level and Forest Functional Level to Windows Server 2003.
On the 2003 DC, went into the registry and navigated to HKLM SYSTEM CurrentControlSet Services NTDS Parameters and verified that the Schema Version is 30. On the 2003 DC, inserted the Windows Server 2008 Enterprise x32 Edition to copy over the adprep folder. I stumbled across my answer through a link with one of the blogs you posted. Since I am running Server 2008 R2.
ADPREP.exe is a command-line tool that extends the Active Directory schema, and updates permissions as necessary to prepare a forest and domain for a domain controller, that runs the Windows Server 2008 operating system.

The schema version has to be 47 and not 44. So I put in the Server 2008 R2 DVD and pulled the adprep folder out and put it on the 2003 PDC and ran adprep32 /forestprep and everything went smooth I made another mistake by making the new Server 2008 DC (during dcpromo) a Global Catalog server. This made transfering the Schema Master role cumbersome.
So not making it a GC fixed that issue thanks again – Omar Mar 29 '10 at 2:07.
Hi Richardsong, Adprep/forestprep is a switch to be run from the command prompt in the schema master of a forest. You will not find forestprep inside the adprep folder because it is a switch. ADPREP.exe is a command-line tool that extends the Active Directory schema, and updates permissions as necessary to prepare a forest and domain for a domain controller, that runs the Windows Server 2008 operating system. The Adprep/forestprep command extends the schema objects that are necessary for the new features of windows server 2008.
You can find these extensions in the.ldf files of the sources adprep directory. However,look into the following links for more information.
