Migrating an Image of Windows Server OS

The following explains the steps required for migrating an image to a IaaS environment when the OS of the virtual server that is operating in the virtual environment is Windows Server.

Before you begin

The procedure explained below applies when the OS that you are migrating is one of the following versions:

  • Windows 2008 R2
  • Windows 2012
  • Windows 2012 R2
  • Windows 2016

About this task

Perform the following steps in the virtual environment and on the OS of the virtual server from which you are migrating the image.
  • Use the console of the virtual environment for operation. Do not connect from outside, such as by using remote desktop, because doing so affects the network settings.

    Example: Start and operate the virtual machine console from VMware vSphere Client.

  • Be sure to make a backup before you change the settings of the virtual environment from which you are migrating so that you can restore it.
