MIGRATING WINDOWS 2003 SERVER ACTIVE DIRECTORY TO WINDOWS SERVER 2008

I currently have a windows 2003 domain with active directory and would like some tips on things to look out for when converting over to the newer server 2008 active directory domain? Also would there be any conflicts to adding the new 2008 domain controller into my existing 2003 forest? Do all the 2003 controllers need to be removed or they will play nicely with the newer DC until I get time to remove them?

Thanks for any advice on a smooth transition

Hi

If the 2003 server is not a small business server you can add member (domain controller) servers without any problem which can coexcist.
So yes, you can remove the 2003 DC after finishing but you are free to choose it running as is.

2003 and 2008 DC's will coexist in the same forest just fine. Like a previous poster stated, as long as the 2003 DC is actually not Small Business Server 2003, you can just add an additional DC and replicate the data.

Thanks everyone!

One last question do I need to upgrade the domain functionality or is that more for windows 2000 domains and is there any drawback to leaving the 2003 DC's in operation?

At some point in the very near future, if it hasn't happened already, Windows Server 2003 will no longer be supported by Microsoft. It support will go the way XP's did recently. I think it is essential to run on a supported OS. With both 2003 and 2008 DC's in the mix the highest level your domain/forest will go is 2003.
