I am trying to retire my first Domain controller machine and created a new DC to hold all FSMO roles in a windows 2012 server environment. I created my new DC, successfully transferred all FSMO and started using it as my DNS as well. My exchange server is also acting as a Global catalog server but no FSMO roles. I turned off the old DC and things are running. However, when I went in to modify GPO, it failed. Seems the SYSVOL and Netlogon folders did not replicate to the new DC. All three servers show up in NTDS settings (I turned the original DC back on) but I can't get it to replicate. I've told it to replicate from selected DC.
What did I miss and what should my next troubleshooting steps be please?
