Upgrading Network Policy Server from Server 2008 R2 to Server 2012 R2

2 Replies

Synopsis: This tutorial will cover a basic "upgrade" path to go from Server 2008 R2 to Server 2012 R2.  This tutorial assumes you have a single Network Policy Server and you are wishing to reuse the same machine name, IP, and settings.  In environments needing high availability, you will need to complete each of the steps below, adding/removing each server being upgraded from your network load balancer.

In a standalone instance, you will experience some downtime as you will have to retire the old machine and setup a new one.

Tutorial

  1. Login to your Server 2008 R2 NPS server
  2. Open up a command prompt with Administrative Privileges
  3. Execute the following command
    1. netsh nps export filename="c:\users\YOURUSERNAME\Desktop\NPS.xml" exportPSK=YES
      netsh nps export
  4. Copy the NPS.xml file to your local machine
  5. Disjoin the NPS server from the domain
  6. Retire the machine
  7. Recreate a new Server 2012 R2 machine with the same name and IP address
  8. Join the Server 2012 R2 machine to the domain
  9. Open up Server Manager and select Add Roles and Features
    Server 2012 - Manage - Add Roles and Features

  21. Execute the following command
    1. Import-NpsConfiguration -Path c:\users\YOURUSERNAME\Desktop\NPS.xml
      Server 2012 R2 - Powershell - Import-npsconfiguration
  22. Head over to Server Manager and select Tools -> Network Policy Server
