Hi,
We have 2 domain controllers, one physical and one virtual. It is time to replace the physical server hardware and I thought I'd take the opportunity to upgrade to 2012 R2 as well.
The current setup is Windows Server 2008 R2 and I see that the current function level is Windows Server 2003, I have no idea why.
I've been researching how to perform this migration but still have a few questions, this will be my first attempt at doing this kind of migration/upgrade.
I have the new server in the rack and have loaded 2012 R2 and all the latest patches.
All of the step-by-step procedures I have looked at only address one domain controller. What would I have to do differently with two dc? Should I have another VM staged and ready to go at the same time?
How transparent is this process to end users, do I have to do bump everyone off the network before performing this migration or can I do it during normal business hours?
As a neophyte how smooth is this process? I mean, do I have to worry that it will blow up in my face and having to spend large $$ to get a consultant to clean up my mess, or does it flow pretty smoothly with little chance of catastrophe?
What are the trickiest parts of this, where are the hidden gotcha's?
Thanks in advance,
Linn
