Can you be a little more specific?  An in-place upgrade is fine on the same box.  If going this route, you need to have the same edition of OS or higher (i.e. standard to standard or enterprise, enterprise needs to upgrade to enterprise).

If you want to reload into a fresh 2008 installation, then you would need to have the same machine name, same CAname, the certificate database, and the CA's private key.  You can use the CA mmc - rightclick CAName- all tasks - backup CA and select the db and private key, or you can use 'certutil -backupkey' and 'certutil -backupdb' commands to do so individually.  During installation you can specify to use an existing key, or afterwards you can 'restore ca' from the same area in the MMC.

Make sure you make a full system backup including system state prior to upgrading, of course.

Well, what I have in place is a server that I call security server where the CA resides.  I am looking to "decommission" that as the security server and have a new 2008 VM ready to replace the 2003 server.

Are you looking to just install a brand new CA and decom the old CA as part of all that? If you do that you will need to reissue all of your certs - you can set up the new root in parallel and deploy that in AD, etc. until you are ready to decom the old CA.

It wasn't entirely what I was looking for but since I am unfamiliar with it, I may not have a given.
