• Upgrade TFS Basic or Express (Basic upgrade)
• TFS Use the Same Hardware (Standard upgrade)
• TFS Use Different Hardware (Advanced upgrade)

I choose to explain the most complex one which is the 3rd one, so there are a lot of alternative paths for this scenario, I choose a specific path to simplify the posts and I will try to mention any alternative paths needed as we go throughout the series. This series is step-by-step with videos and images and in the last post I will put one video for all parts and summary the whole series, I will try to mention some considerations that you could take care of them while you are upgrading. Let’s start by examine the table of content for this series in details:

• Part 1 – Introduction.
  • Introduction.
• Part 2 – Prepare SharePoint for the new system.

• Part 8 – Upgrade TFS 2012 Build Service.
  • Upgrade TFS 2012 Build Service.
• Part 9 – Summary.
  • Summary.

The chosen upgrade scenario is consistent of 3 machines, one as a Domain Controller, the second as TFS 2010 that contain most components of TFS and the third machine is a new empty machine, see the following image:

Machine 1: Domain Controller

• Windows 2008 R2 SP1 with latest update
• Active Directory and DNS

Machine 2: TFS2010

• Windows 2008 R2 SP1 with latest update
• MS SQL Server 2008 R2 SP1
• MS SQL Server Analysis Service 2008 R2 SP1
• MS SQL Server Reporting Service 2008 R2 SP1
• TFS 2010 SP1
• TFS Build Service 2010
• MS SharePoint Server 2010 SP1

Machine 3: New machine

• Nothing

In this upgrade scenario I will use the existing domain controller, I will also leave the SharePoint 2010 on the old TFS 2010 machine and use that machine as SharePoint server for the new environment, the new system will use Windows Server 2012 and SQL Server 2012 as well, see the following image:

Machine 1: Domain Controller

• Windows 2008 R2 SP1 with latest update
• Active Directory and DNS

Machine 2: TFS2010

• Windows 2008 R2 SP1 with latest update
• MS SQL Server 2008 R2 SP1
• MS SQL Server Analysis Service 2008 R2 SP1
• MS SQL Server Reporting Service 2008 R2 SP1
• MS SharePoint Server 2010 SP1

Machine 3: TFS 2012

• Windows 2012 with latest update
• MS SQL Server 2012 SP1 Enterprise
• MS SQL Server Analysis Service 2012 SP1
• MS SQL Server Reporting Service 2012 SP1
• TFS 2012 Update 1
• TFS Build Service 2012

In the next posts I will start to explain how to perform this scenario.
