the problem is that the DNS for the domain is also the mail server for the domain and there is a need to migrate to a new subnet - so far I have aliased the new IP address onto the nic (via ifconfig) - I'm just not sure haw to tell the rest of the world that new_ip may be found at ether_addr. Once this has been achieved the DNS records can be updated to reflect the new subdomain.
