Is there any harm in changing the IP address of the public DNS servers temporarily?  It would only be for a couple of hours.  Just enough time to convert the server from physical to virtual.

If you are talkin about changing your internal DNS with external DNS then yes this will kill your complete network as your network dns knows about your internal network.. External dns will just help in resolving external sites.
All AD exchange, machine, server dns entries are in your local dns..

You are changing a server's IP address to point to another location? What does this server run? If the server runs certain services you will not be able to access these services unless you moved them to another server.

Technically speaking you should not see any issues.

It all depends if you have someone on the outside trying to come into your LAN or trying to access a web server.

We are trying to virtualize all of our servers.  We are running VMware and we are wanting to p2v our public DNS servers.  We hired consultants to setup the vmware environment and they created a DMZ network within vmware for our public DNS servers.  However, in order to p2v the servers they need to be on the same network as vCenter.  In order to put it on the same network as vCenter we need to change the vlan and IP address of the DNS servers just long enough to virtualize them.  Probably won't be more than an hour.  We have redundant public DNS servers so it should not affect users.
