Moving Certificate Services from 2000 to 2003

I am running Windows 2003 on my DCs. My CA is installed on a Windows 2000

server. I would like to move my certificate services from 2000 to a 2003

server. I saw the article

http://support.microsoft.com/kb/298138/en-us

but it says I have to upgrade the CA to 2003. I cannot do that because of

other services running on the box.

I want to get my CA on 2003 so it will support the autoenrollment of

certificates feature. Does anyone know if...

I can move my CA to another 2000 box and then upgrade the new CA to 2003

with minimal disruption?

Any assistance is appreciate.

Thank you.
