We've got a domain controller that's become corrupt and it's time for an upgrade anyhow, so we've got a new system to use. We want to move all existing users, groups, policies, computers - anything and everything - to the new server.
There's plenty of methods to do this, but here's the catch, we want to use the same domain name so we can't have them on the same network and get them talking.
Is there an export/import method to do this? Or some way I'm not finding to have them both on the network together?
