We are in the process of doing a DHCP migration from a Server 2003 32-bit domain controller to a Server 2008 R2 domain controller. Both are also DNS servers. Our plan is fairly straight forward:
1. use the Microsoft prescribed method to migrate the DHCP databases
2. switch out IP addresses between the two servers.
The original server 2003 server is also a primary DNS server in the scopes. We believe that if we take that IP address and just move it to the server 2008 server along with the DHCP role and database we should be OK.
Are there any gotchas or items we should be made aware of? Things we should watch out for or things that could help us make this project go smoothly?
