How to upgrade Windows Server 2008 R2 to Windows Server 2012

Windows Server 2008 R2 to Windows Server 2012 Upgrade guide

 

Personally I always want to upgrade to the latest Microsoft product available but for stability reasons I always wait a few months before to make sure everything is strong & stable.  Today I present you a step by step guide on how to upgrade your current Windows Server 2008 R2 to Windows Server 2012.  This guide is made with a very basic version of Windows Server 2008 R2, but this will work with any version with any roles or features installed such as Active Directory.

 

  1. First step is to insert Windows Server 2012 CD in disc drive or mount ISO file.  And Then click on ‘install’.

  2. Setup will now ask you if you want to download windows updates while upgrading, click ‘no thanks’.  You can do them later, it is a long process.

  5. On the next screen, since we are upgrading from Windows Server 2008 R2, we want to keep our settings and files.  So we select ‘upgrade’ instead of ‘custom’ installation.
