You mean aside from the part where the backup DC would see the other four DCs turn off and then turn back on with a 15-minute-old copy of the data? Data that it thinks should already be replicated because it’s operating in the present, not the past?
Don’t do it. If you lose the four main DCs, seize the roles on the DR domain controller and create fresh ones.

We have 5 DCs, all VMs, in a Windows 2012 R2 Forest/Domain functional AD. We have one forest, one domain. One of these DCs is running at a backup site about a mile away. I would like to use VMware Replication to keep copies of the other four DCs at the same location. The replication would be set with an RPO of 15 minutes. In a disaster scenario for our data center, the DC at the other site would be the only one standing, but I would bring up the replicated DCs, one at a time, starting with the PDCe. The only other thing I would need would be to confirm that the IP configuration holds or set it correctly if needed. Everything else is taken care of, such as physical network, DNS, etc. We already know we can recovery services such as this at the other site because we have tested it. Also, VMware replication would not be used as a replacement for backups, and we have other AD DR plans which have been tested using conventional backups. I simply want to know, from an AD perspective if this is a bad idea. The platform is irrelevant. We could just as well be using Hyper-V, but I will also check on the VMware Forums in case there’s something I should know related to VMware’s solution. Thanks in advance for any feedback.
