I have in a test environment (where network access to our production environment was not possible, or desired). I'm just wondering in your test, if both domain controllers were restored authoritatively, which would effectly raised the object update sequence number on each domain controller's AD database. I just restore them without choosing to restore authoritatively because there is no need to raise the ad object numbers, there will be no domain controller pop in with any argument, over which object is the master copy etc. However when I have perfectly good backups of all domain controllers and can restore them, which for us is very fast. We practice Distaster Recovery every six months, and when we restore a single server, we have recovered it authoritatively. If you have more than 2 in your production environments, so that in your test you have not restored all operations masters, then you may need to do some work to recover those operation roles. Is your VM restore, restoring them "authoritatively"? Here is the thing, if you have 2 domain controllers in your environment, and you restore "both", there is no need to update the USNs. We regularly test restoring 2008 R2, however I have not restored 2012R2 DC's yet, so could be there is something I need to see.
