I have a small home network with a W2K3 SP2 Domain Controller with DNS and DHCP. This is running on a Dell PowerEdge 1300 that I'll call SvrA. I've just purchased a used HP DL380 on which I've installed W2K3 R2 SP1 that I'll call SvrB. I want to promote SvrB to be a Domain Controller, enable and configure DNS and DHCP on SvrB to replicate SvrA, and demote SvrA.
I've looked at ADPrep and RepAdmin as mentioned in http://technet.microsoft.com/en-us/library/cc773360(WS.10).aspx
My concern is the mix of W2K3 SP2 and W2K3 R2 SP1. What caveats should I be aware of? Can I use the ADPrep from R2 on my SP2 DC without any problems? I figure I could use the brute force method of shutting down SvrA and creating a new DC/Forest with SvrB, but I'd like to step through the correct procedure, if at all possible.
I appreciate any help...
