How to: Move from a Single-Server to a Dual-Server Deployment

In order to support a larger number of projects or improve Team Foundation Server performance, you might want to move from a single-server to a dual-server deployment of Team Foundation Server. In this kind of move, the original Team Foundation Server installation is converted into the Team Foundation application-tier server, and a new installation of Team Foundation Server is configured as the Team Foundation data-tier server. The data from your original Team Foundation Server deployment is restored to the new environment. In order to successfully perform this kind of move, you must not:

  • Change the service accounts during the move.

  • Change the name of the Team Foundation Server when you convert it to act as the Team Foundation application-tier server during the move.

  • Change the domain of the Team Foundation Server during the move.

  • Install the Team Foundation data-tier server in a different domain than the original Team Foundation Server deployment without sufficient trusts.

Before you move your Team Foundation Server deployment, you need to prepare for the move. You must complete many steps when you move from a single-server to a dual-server deployment. This topic provides links to some of these steps. Read through and consider whether you want to print all the required steps before you start the move. To move from a single-server to a dual-server deployment, you must perform steps such as installing new instances of Team Foundation Server, backing up and restoring data, re-creating or migrating user accounts and service accounts, and reconfiguring your servers.

Required Permissions

To complete these procedures, you must be a member of the Administrators group on the old and new servers and a member of the Team Foundation Administrators group.

To prepare the single-server Team Foundation Server deployment to move to a dual-server deployment

  1. Back up all the Team Foundation Server databases.

    For more information about how to back up Team Foundation Server, see How to: Back Up a Team Foundation Server.

    NoteNote

    If you have created any Windows SharePoint Services custom site definitions, custom site templates, or custom Web parts and you want to keep your customizations, you must back them up also. For more information, see the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=63543).

  2. Back up the Reporting Services encryption key. Make sure that you store the encryption key in a secure location on a different computer that can be accessed in the domain.

    For more information about how to back up the encryption key, see How to: Back Up the Reporting Services Encryption Key.

To uninstall Team Foundation Server components

  • Uninstall Team Foundation Server components from the single-server Team Foundation Server. For more information, see How to: Uninstall Team Foundation Server Single-Server Deployment in the Team Foundation Installation Guide. The most current version of the Team Foundation Installation Guide is available on the Web at the MSDN Online site (http://go.microsoft.com/fwlink/?linkid=40042).

To install Team Foundation Server in a dual-server deployment

  • Install a dual-server Team Foundation Server deployment. Make sure that you install the Team Foundation application-tier server on the server that used to be the Team Foundation Server single-server deployment. For more information, see Overview of Team Foundation Server Dual-Server Deployment in the Team Foundation Installation Guide. The most current version of the Team Foundation Installation Guide is available on the Web at the MSDN Online site (http://go.microsoft.com/fwlink/?linkid=40042).

To save Reporting Service installation IDs and stop services

  1. On the new Team Foundation application-tier, retrieve and save a list of the Reporting Service installation IDs.

    1. Open the Command Prompt window and change directories to drive:\%ProgramFiles%\Microsoft SQL Server\90\Tools\binn\

    2. Run RSKeyMgmt -l.

    3. Note the installation IDs and print a list or save the list in a safe location.

  2. Click Start, click Administrative Tools, click Services, select the TFSServerScheduler service, and then click Stop, if not already stopped.

Rename the Team Foundation Data-Tier Server and Activate the Team Foundation Application-Tier Server

After restoring the Team Foundation Server databases, you must configure the Web.Config file with the name of the original Team Foundation data-tier server before you can use the TfsAdminUtil command-line tool to rename the data tier.

To modify the Web.Config file to reflect the original Team Foundation data-tier server name

  1. Modify the services web.config file and replace the Team Foundation data-tier name with the old Team Foundation data-tier name as follows:

    1. On the new Team Foundation data-tier server, open a Command Prompt window and change directories to drive:\%ProgramFiles%\Microsoft Visual Studio 2005 Team Foundation Server\Web Services\Services.

    2. Open the web.config file in this directory in Notepad or any text-based editor.

    3. In the connection string value, under the appSettings node, change the Source parameter to use the original Team Foundation data-tier server name. For example, the following line must be modified from:

      Application Name=TeamFoundation;Data Source=newTeamFoundationDataTierServerName;Initial Catalog=TfsIntegration;Integrated Security=True;Persist Security Info=False

      To

      Application Name=TeamFoundation;Data Source=oldTeamFoundationDataTierServerName;Initial Catalog=TfsIntegration;Integrated Security=True;Persist Security Info=False

    4. Save the Web.config file and close Notepad.

    NoteNote

    The TfsAdminUtil RenameDT expects that the connection string in the services Web.config file refers to the old Team Foundation data tier server name. The server name must be restored to the web.config file for the command-line tool to run correctly.

  2. From the Command Prompt window, change directories to drive:\%ProgramFiles%\Microsoft Visual Studio 2005 Team Foundation Server\Tools and type the following command:

    TfsAdminUtil RenameDT newTeamFoundationDataTierServerName

  3. If the new Team Foundation application-tier server has a different name than the original Team Foundation application-tier server, you must update the TFSIntegration database with the new Team Foundation application-tier server name, and then rename the application-tier service interface registration entries to point to the new Team Foundation application-tier server.

    NoteNote

    This step is required only if the new Team Foundation application-tier server has a different name from the original Team Foundation application-tier server.

    1. On the new Team Foundation application-tier server, open a Command Prompt window.

    2. Change directories to drive:\%ProgramFiles%\Microsoft Visual Studio 2005 Team Foundation Server\Tools.

    3. At the command prompt, type the following command:

      TfsAdminUtil ActivateAT newTeamFoundationApplicationTierServerName
