    We have one old server 2016 and we got a new server 2019 The new server is setup and promoted as DC2 and AD DS is synced. Just need someone to go over the configuration and see if everything is setup properly. And if it’s ok to demote/turn off the DC1. Existing physical server DC1 had ERP application on it so I have virtualized this DC1. And added it to hyper-V in the new server DC2. I want to just turn off the physical server. So I will have DC2 physical server as our main primary DNS host. And the VM -DC1 will be secondary DNS with the applications. Or vice versa. We can leave VM-DC1 as primary DNS and DC2 as secondary.
