I need to raise the functional levels of our Domain and Forest to Windows Server 2012<br />
<br />
I have 2 Windows 2012 Domain Controllers, DC01 &amp;&nbsp;DC02, running on VMWare &nbsp;(Both are not R2) <br />
<br />
The Domain and Forest Functional Level are currently at Windows Server 2003 (reason unknown)<br />
<br />
Questions:<br />
1. What tools should I use to check for problems before the upgrade?<br />
2. I have verified that AD replication is healthy using repadmin/replsummary . &nbsp;Do I need to perform the upgrade on both DC's or does the upgrade replicate?<br />
3. We use Veeam backup. What would be the best practice to reverse the process in case something goes wrong?<br />
4. I have read that this is not a disruptive procedure and can be performed during a workday. Is this true?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
