DNS on Demoted Domain Controller

I have installed two new Windows server 2008 domain controllers that are replacing an older Windows Server 2003 Domain controller. I am ready to demote the old domain controller but realize that all clients are pointing to the old server for DNS.  The new domain controllers that I installed have already been set up with DNS as well and everything is replicated. DNS on the servers is Active directory integrated, so I believe that when I demote the old Domain Controller it will lose DNS functionality. All clients would then stop being able to connect to DNS, so I believe that I have two options:

1. Hold off demoting the old domain controller until we can change DNS settings on all clients in the network.
2. Remove DNS from the old domain controller, then demote it, and then add DNS again, setting up a Stub or Secondary Zone to replicate the primary zone that is now on the new servers.

The second option is better because it would be much easier. But I don't want to go that route if it would cause any problems. Eventually I would plan on adding the two new DNS servers to the settings on all clients. Any input would be appreciated.
