CNAME record for Decommissioned Domain Controller: Best Practice?
Posted on 2014-03-05
I have some domain controllers I am decommissioning in a rather large environment; I am replacing them with new DCs, and ultimately will be using the former DC IP addresses. This addresses alot of the issues around statically addressed machines/devices. But in thinking of a lot of unknowns, I wonder how to get apps to function that may be specifically binding to DCs by FQDN or hostname.
Is it feasible to create an A or CNAME record for the old server name to point to the new one? Will this cause kerberos issues or problems with our PKI Infrastructure? If anyone has any information on this that would be helpful - trying my best to use best practice here and not anything too "hack-tastic"
