Windows 2003 R2 Domain Controller Upgrade to Windows 2008 R2

Hi All,
I have an existing domain consisting of 2 Win2003R2 servers. One is a domain cotroller/DNS/DHCP, etc. and the other (joined to the domain), hosts a couple of SQL Databases.
I need to upgrade the existing domain controller on the existing hardware, to Win2008 R2, leaving the SQL server on the win2003 R2. So in few words I would have a Win2008R2 domain controller and the existing Win2003R2 with SQL.
The hardware is going to be the same.
What must be done in order to accomplish this?
Thank you in advance and best regards to all

Are you planning to use the existing hardware? In-place upgrade?
Here is an option but you need additional hardware -http://social.technet.microsoft.com/wiki/contents/articles/2903.active-directory-active-directory-upgrade-high-level-steps.aspx
If you don't have additional hardware, you can perform an in-place upgrade. Keep in mind that Windows 2008 R2 is only available in 64 bit. You need to upgrade the schema first.

In addition,
After completing the forestprep check the schema version and wait for the completeing the replication and then run the domainprep.
How to check the schema version?
Schema version for new operation system
Find the Schema version for the operating systems

Hi All and thanks for the replies.
I will be using the same hardware. The existing server is 32-bit so I won't be able to do an in-place upgrade and also there is no point in doing domainprep if the server is going to be re-formatted. That is my dilemma. I am not sure what to do with the server hosting SQL.
I was thinking:
1) dis-join the SQL server from the existing domain.
2) install Win2008R2 onto the domain controller and setup new AD, etc.
3) Join the SQL server to the new AD domain..
That should work, shuldn't it?
Thanks again
