So I'm needing to duplicate our DC for a test environment. I'm having an issue on deciding which way is the best way to remove the test DC from the production forest.
We currently have 2 DC in our forest. I was able to successfully add the test DC (third one) to our forest by using DCPROMO which added it to our production forest. It replicates fine.
My question now is: Do i run dcpromo to demote the test DC or should I just kill it off and clean up the meta-data on my production forest. I understand that i would need to seize the FMSO roles on the test DC to make it the master roles.
My concern with demoting the DC is that it will remove all the users, groups, setting's, GP. If i decide to demote it from production, i would have to run DCPROMO to make it a DC again, right? Will that erase all the information that was replicated from the production?
I think disconnecting the test DC from the production seems like it would work much better since the test DC is still technically active in a stand alone mode and I can then seize the roles. The only thing i would need to do is clean up the meta-data from the production and test DC.
Has anyone ever tested this out??
