Active Directory migration from Windows Server 2000 to Windows Server 2008

Hello.  We have two Active Directory Servers (using Windows Server 2008).  The primary server works fine, but the second server is not running correctly as a logon server.  I am trying to fix this, but am considering another approach to the problem... an upgrade to Windows Server 2008).

Can I add two Windows Server 2008 servers as additional DNS/DHCP/Logon servers (configured in WIndows 2000 mode [I saw something about this during the OS install]) and after they are up and running as failovers, promote them to be primary servers, take the original 2000 servers out of the equation, and then switch the 2008 instances to Windows Server 2008 mode (from 2000 mode)?

Thank you.

Here is a step by step guide on the procedures of migrating to Windows 2008 server. The steps say for 2003 but the procedures are the same.

Thank you for the link.  My situation, though, is just a bit different.  I want to migrate to Windows Server 2008, using new hardware.

Can I:
1)  add two Windows Server 2008 servers as additional DNS/DHCP/Logon servers (configured in WIndows 2000 mode [I saw something about this during the OS install])
2) and after they are up and running as failovers, promote them to be primary servers,
3) take the original 2000 servers out of the equation, and then
4) switch the 2008 instances to Windows Server 2008 mode (from 2000 mode)?

Would these be the steps of the migration or am I missing something?

Thanks.
