Upgrading Server 2012 R2 to Server 2016


Server 2016 migration guides are not available yet (26 October 2016). server2016-01So this post will explore a domain joined physical Server 2012 R2 to Server 2016 upgrade. This is from Data Center to Data Center edition. The 2012 R2 server has the following roles:

First I mounted the image:

server2016-02

Being a Hyper-V host, I live-migrate the production VMs to other Hyper-V hosts. All other VMs are shutdown. Then I run the setup.exe

server2016-04

and download the latest updates, enter the product key

server2016-05

Depending on the product key you enter, the next screen shows the corresponding Windows Server edition. I select Data Center (Desktop Experience). This is the option that provides a GUI. For more information on Server 2016 GUI options see this post.

accept license terms, and attempt to select to keep personal files and apps (not default option)

Issue with Windows Edition and keeping personal files and apps:

However, that option is not available – un-clickable. The message at the bottom complains about different Windows Editions. That’s not true. As you can see in the background, a PowerShell command that indicates that this server is running 2012 R2 Data Center Edition ūüė¶

There’s a single external vSwitch bound to the NIC team with a vNIC for the parent partition

NIC teaming is not supported during upgrade:

Now breaking the team, means this upgrade cannot be done over an RDP session. To do it remotely you need console/baseboard access. Most modern servers like Dell, HP, and UCS do.

It then proceeds to download the updates:

Again references to Windows 10 in the middle of Server 2016 installation/upgrade
