Migrate Hyper-V Clustered server to new AD domain
-
We have 2 HP servers, one one AD domain, with Hyper-V and clustering enabled. From the parent company, we got instructions that all local DCs should be decommissioned soon and migrate all local servers to be part of their global AD.
I am looking for the safest option to move this servers to the new domain, what i think that needs to be done are;
Take backup of VMs (Veeam free), and break the cluster, join the servers to new domain and create it again.

I would do fresh installs, not change domains. AD DCs take effectively no effort to build and this should be seen as a chance for a fresh install.

Clustering from HyperV should never be enabled with Active Directory controllers!! That puts them at risk rather than protecting them.

Are you meaning to say that AD controllers should never be hosted on a Hyper-V Cluster? ... or what?

No, they can be on a cluster, that is fine, as long as the cluster is broken for the Domain Controllers. Just like Exchange, SQL Server or anything else with a database or similar usage can't be clustered from a hypervisor. Nothing weird about AD, very few workloads are crash safe on a HyperV cluster.
-
So, for example, you have Exchange, SQL Server and AD DCs on a HyperV cluster along with web servers, file servers and other "clusterable" workloads. You can create the cluster for those and tell it not to failover for the database driven ones (SQL, Exchange and AD.)

The host servers are not DC. Its just part of a local domain, now needs to be changed to a global group domain. http://namitguy.blogspot.ae/2012/03/moving-hyper-v-cluster-to-new-ad-domain.html also explains about this.
I wish i could get a lab to test this first without screwing up my dev servers!
-
@Ambarishrh At least they ar dev servers!

-
@DustinB3403 Good point... They could also be Development servers for the Developers to program on...
-
Sorry for the confusion- its a development server, but i still need to make sure that these are updated with minimal downtime. I am trying to push the AD changes to some other time at least wait for the dev team to complete the tasks in hand, but not very sure if they will stop it just for us
