Hi, As Exchange 2010 rely on Windos 2008 R2 or SP2 with x64 bit, you must have to migrate Exchange 2003 first and the can migrate windows 2008 R2 for domain controller.

Hi Anil, Thanks for your reply. So i can't migrate 2003 to 2008 first in exchange 2003 environment. I have to migrate exchange 2003 to exchange 2010 after that i can migrate windows 2003 to windows 2008 right.

If yes, it can’t be accomplished The resources below can provide more help: System Requirements for Exchange Server 2003 Exchange Server and Windows Server 2008 Exchange Server and Windows Server 2008, Part II Mission Impossible: In-Place Upgrading Microsoft Exchange Server 2007 from Windows Server 2003 to Windows Server 2008James Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com
