according to this link it is possible
http://www.microsoft.com/windowsserver2003/evaluation/whyupgrade/supportedpaths.mspx
however it does also say
"When upgrading operating systems, a clean install is recommended as best practice."

Hi,
I did this procedure many times, on production servers as well. No problems.
Just run setup from windows 2003 ent CD when you in windows 2003 std.
You need to install win2003 ent with same service pack level - so if you have win2003 std - use windows 2003 CD with sp2
Of course, the first rule of each upgrade: make sure you have good backup.
