New Windows 2008 R2 server replaces old 2003 DNS server

I thought I would first join the new server to the domain and then demote the old server.
I started by trying to run adprep32 /forestprep  from the Windows 2008 R2 CD on the old Server but I get a message 'program too big to fit memory'.
Is there an easier method since I do not need the old server at all?
If not, any suggestions?

I found this from Tony (good friend) over at the Technet Forum  http://social.technet.microsoft.com/Forums/en/winserverMigration/thread/fea95c62-5954-4a67-89c8-4d883c0f7eb7

Do you have another disk that you can try to pull adprep32 from?

Thanks

No I do not. I was thinking of upgrading the server for one day to windows 2008 R2 and then the Active directory should be upgraded automatically, so that I will be able to do what I want. I will not activate it, so I should not have a problem. What do you think?
Or else, do you have a link hwere I can download the software?
