TECHNET EVAL to PRODUCTION USE WITHOUT Reinstallation (technet user!)

I built a 2003 Server using my technet 2003r2 Server evaluation copy. I

would

like to make this a production server now. I'm in the process of purchasing

a new copy of (open value )Server 2003r2 and would like to use this license

without

having to rebuild the server. Is there a process to apply the new license I

purchased to the existing evaluation copy? I intend to use the Exchanage

server 2007 as well. Thank you
