Do you have additional Domain controller?
If not promote this 2k8R2 as additional DC

If I read the question right you want to migrate the domain controller functions from the 2003 server to the 2008 R2 and remove the 2003 at the end?

Here is a good step by step document with screen:

If you wish you can use my document. But this is for 2000 to 2008. Instead of 2000 place your 2003 box :)
You do not need to create new DHCP scope(s) from my instruction, instead of that you can use this MS article to migrate DHCP database at http://support.microsoft.com/kb/962355

Domain prepartion manual you will find in the attachment. Hope it would be useful

Dear All, Will there be any problem\effect on my Exchange mail system or Do i have to take care anything in Exchange server 2007?

If the exchange server just stays on its member server it would not make any problem. I would to be sure have at least exchange 2007 SP2 or better SP3.
