Virtualization Idea

Hi Guys.

I'm doing some VM work and need your input.  

I have three new servers Tyan1, Tyan2, and Tyan3.  
I have old servers that I want to virtualize.
Please see attached document for details about these servers.

My main question is migration DC1 and DC2 to VMs running Windows Server 2012 Std (from Windows 2008 R2).

what is the migration process to go from DC 2008 R2 to DC 2012 Std?  Should I demote and decommission DC2 first, then migrate DC1 to 2012 on the VM, then create a new VM for DC2 and assign it as a global catalog?

The rest (file servers, endpoint, wsus) I've got it covered.

There is no "right" answer here, as there are multiple legitimate approaches you can take. But if it were me, I would bring up both new DCs as VMs, verify replication, transfer FSMO roles, then decommission the old CCs. Decommissioning old CCs before new ones are online could complicate replication and insert multiple single points of failure.

The recommended way and best practice, is to create a new server, promote to DC, and transfer FSMO roles.

If however, you cannot or do not want to do that, you could P2V.

Hi Cliff,

As Andrew mentioned, its safe to create a new VM and promote it as a domain controller.
However, please ensure that you follow the best practicies specific to virtualizing domain controllers. Its very important and if you miss, you may end up in a mess.

does that link apply to Server 2012 std?  I'm upgrading the OS as well, not doing P2V.
