Hello fellow sys admins! In the following post, we will stroll through an in-place upgrade from Windows Server 2008 R2 to 2012 R2. Let us dive right in.

The initial step in any upgrade is to get the Installation Media. If you are utilizing a Virtual Machine, then it’s as easy as including the ISO to the Virtual CD-R Drive, either utilizing the Hyper-V maker settings or the VMware console. If you are updating a physical server, then simply unload the ISO and copy it to either a secondary drive or flash drive, or you can simply run it from a network share.

In our situation, I am running the setup from a network share. In both cases, the upgrade procedure is the very same; there is no distinction in between the VM OS or physical server OS as all of us understand so well.

Therefore, as I pointed out previously. I have actually unloaded the ISO utilizing WinRAR.

Afterwards, I simply ran the s etup.exe from inside the OS. A little pointer is to make certain you do not have any other users logged into the server in any method, RDP or console, considering that the requirement check will stop working and you will need to go through the setup once again.

Once in the Setup Wizard, we will download the current updates, which are needed in order to bring the server to the most recent suitable state for updating to Windows Server 2012 R2. This is an extremely crucial action, which many people select to overlook, however it will conserve you a great deal of trouble after you update.

Next, we will select the variation of Windows Server 2012 R2. In our case, we are going from Windows Server 2008 R2 Standard Edition to Windows Server 2012 R2 Standard Edition.
