Windows 2000 to Windows 2003

I am in process of doing a server migration.

Currently i have two DC primary and secondary.

I’ve read materail on DCPROMO, but affaird of using it because i don’t want to mass up the production servers.

If someone can guide on this i would GREATLY appreciate that.

I’ve already joined my new server to my existing domain.

This is what i understood….

1. Run dcpromo on new server and promote them into the existing domain. this move all the grp policy and user accounts to servers?
