I have completed the process with the dfsrmig commands successfully and everything was prepped, I was able to move all FSMO to the new server but cannot demote the old server. Communication between the old server and new server is hit or miss. When I run netdom qurey fsmo all roles are showing on new server (both servers). However, seems to be a problem with AD. I cannot find it. dcdiag shows duplicate name - I have hyperv setup and a virtual switch. All IP addresses are on the virtual switch and the physical nic is selected to use the virtual switch (no ip on physical nic). I need to demote the old server gracefully (not wanted to use forceremoval switch) as I believe there are issues in DNS. Any direction appreciated.
