Upgrading from Windows 2008 R2 Hyper-V to 2012 R2 – NIC Configuration

In this post I will show you how to move a Hyper-V Virtual Machine from one Hyper-V Server to another without
the use of Live Migrations. If find this technique very useful when I am swapping out hardware and just need
a simple process to follow to get the guest instances stood up on the new farm.

This can of course be fully automated but the purpose of this exercise will be to show how to do it manually.

Here are the steps I generally follow:

1. Build the new Windows 2012 or R2 Hyper-V Server
2. Download and Patch with all updates from Microsoft (The purpose of this is not to show all the updates)
3. Download and install the latest Firmware and Drivers for the Hypervisor

Run this NIC Configuration Script. I run this on all of my Hyper-V implementations in production

Here is the source for the script:

This Script will perform a base configuration of the Network Adapters on a new Hyper-V Host Server

THis Script has been used in production and only lacks some error control at this time.

It will work as is — You just need to watch your Adapter Configuration and what you want to team up…

Ethernet, Ethernet 2 etc.

1. Ok so let’s start there we will take a new Windows Server 2012 R2 Server as our Target Server the only role
   that has been added thus far is the Hyper-V Role. DO NOT CREATE the VSWITCHES in the WIZARD. We will
   Do that ourselves with this script

   As we can see from the Screen Shot above we have a default Networking Stack Configured at this time

   For this Lab Environment I made a few changes to my default script

   I just change the script to run against a Single Ethernet Adapter and Comment out the bottom where the VLAN’s

   Are defined.

    

   NOTE: The Script will fail to run without the Hyper-V Role being installed first. This is because it relies on
   the Powershell Module for Hyper-V to create the VSwitches and Virtual Adapters.

1. I have staged the Script in c:\Post-Install\001-NICConfig\Hyper-V_ProdNetworkScript_V1.0.PS1
2. First open an Administrative PowerShell Prompt
3. Then type Set-ExecutionPolicy unrestricted
4. The type cd \post-isntall\001-NICConifg
5. The type .\Hyper-V_ProdNetworkScript_V1.0.PS1 When Prompted say Yes
6. Type ncpa.cpl to open the Networking Control Panel

   
   You will see that we have a production ready Networking Configuration now setup for this Hyper-V Host. Obviously your configurations
   will vary. But this is a great starter script. Hope you Enjoy!!
