How to upgrade from SCVMM 2012 SP1 to 2012 R2

Lukas BeranLukas Beran

Because I finally had a chance to upgrade System Center Virtual Machine Manager 2012 SP1 to the latest 2012 R2, I wrote it to this guide.

SCVMM is currently running on Windows Server 2012. So within this upgrade I will also upgrade Windows Server 2012 to 2012 R2. Important (and unpleasant) is that SCVMM does NOT support inplace upgrade, so it’s not possible to upgrade it directly. First you need to uninstall current version and leave the database and then install the new version. It’s unpleasant, but not unsolvable and it’s very well documented.

Before you uninstall SCVMM, you need to uninstall all rollups of SCVMM. You can find them in Windows Updates (Control Panel – Programs – Programs and Features – Installed Updates). Now you can uninstall SCVMM from Control Panels or using SCVMM installation media where you choose Install in the first step and then Remove Features. In next step choose VMM management server and VMM console. And next keep checked Retain database.

After uninstallation of SCVMM you have to uninstall ADK (Assessment and Deployment Kit) as well.

After that I did inplace upgrade of Windows Server to the latest Windows Server 2012 R2 Update. After the upgrade I installed all available updates.

Before SCVMM 2012 R2 installation you have to install new version of ADK for Windows 8.1. Now you can install SCVMM 2012 R2. You need to install both features – VMM management server and VMM console. When you are configuring database, select to use existing database – don’t create new. After that you will see message that the database was created in older version of SCVMM, but you can upgrade the database to 2012 R2 version. Then add service account and check predefined library address. When adding service account, add the same account as you added before, because data are encrypted using the old account and if you add new different account, you will not be able to recover old data from your database.

Now you are ready to use new System Center Virtual Machine Manager 2012 R2. I recommend to check and update agents on your Hyper-V hosts.

My primary focus is the security of identities, devices and data in the cloud using Microsoft services, technologies and tools.
