This past weekend, I upgraded my Team Foundation Server (TFS) 2008 environment to TFS 2010. I also upgraded the TFS project sites to SharePoint Server 2010.
Why the SharePoint upgrade?
The TFS project sites previously ran on Windows SharePoint Services 3.0 (WSS v3) -- not Microsoft Office SharePoint Server (MOSS) 2007 -- and, in fact, most of them were originally created with TFS 2005 and WSS v2. [Refer to one of my previous posts for more details on the somewhat painful experience I had upgrading my TFS environment from WSS v2 to WSS v3 (which was really my own fault).]
In the past, I have generally recommended MOSS 2007 over WSS -- due to the numerous additional features and capabilities of MOSS 2007 over WSS -- but when it came to TFS, I didn't see any compelling reasons for using MOSS 2007 for the TFS project sites (unless you simply wanted to leverage an existing SharePoint farm for your TFS projects).
In other words, with TFS 2008, you didn't get any additional functionality on your TFS project sites by going with MOSS 2007 -- unless, of course, you customized your project sites with MOSS 2007 features.
However, unlike TFS 2008, the new version of TFS has some great features that are enabled via MOSS 2007 (and SharePoint Server 2010), namely dashboards. While the dashboard functionality in TFS 2010 works -- to a limited extent -- with WSS 3.0 (or SharePoint Foundation 2010), you'll have to open the corresponding Excel workbooks, rather than viewing the dashboards directly on each TFS project site (via the Excel Services feature in MOSS 2007 and SharePoint Server 2010).
Consequently, when it came time to upgrade to TFS 2010, I knew I also wanted to upgrade the TFS server from WSS to SharePoint Server 2010.
Preparing for the Upgrade
Using the pre-upgrade checker for SharePoint Server 2010 and the Test-SPContentDatabase cmdlet, I confirmed my TFS project sites did not present any issues with upgrading to the latest version of SharePoint. Fortunately, the TFS product team did not create a custom site definition for project sites, but rather used the out-of-the-box Team Site with a little bit of customization (e.g. custom Web Parts and document libraries) -- which means the upgrade process to SharePoint Server 2010 is relatively simple.
Note that in the "Jameson Datacenter" (a.k.a. my home lab), I use a dual server configuration for TFS -- an application-tier server and a separate database server. The "data tier" only runs SQL Server (Database Engine and Analysis Services), while the "application tier" runs the other services (i.e. TFS, WSS, and Reporting Services).
While there are certainly many organizations out there that install everything they need for TFS on a single server, I strongly recommend you "isolate" SQL Server as much as possible in your Production environment. This makes it much easier to monitor and troubleshoot the environment, as well as scale the solution over time as your needs grow.
This recommendation really applies to most products that depend on SQL Server -- not just TFS. There are a few scenarios where I consider it acceptable to run SQL Server side-by-side with other products and technologies, but in general, you should try to isolate it whenever practical.
I should also point out that this is just my recommendation. According to the TFS installation guide, a single server is recommended when you have less than 500 users. On the other hand, I don't believe that official recommendation covers running SharePoint Server 2010 on the same server -- since the SharePoint team states a minimum of 8 GB of RAM for any production deployment of their latest version.
As I've mentioned before, in the "Jameson Datacenter", BEAST is my "Production" SQL Server instance, while CYCLOPS is the corresponding TFS server. Consequently, when it came time to upgrade to TFS 2010, the first thing that I did was build out two new virtual machines (BEAST-TEST and CYCLOPS-TEST) to test the upgrade. I also learned a few things during the process of upgrading the Test environment that made the subsequent upgrade of the Production environment go very smoothly.
In general, I followed the TFS installation guide to perform a "migration" upgrade of TFS. However, there were a few steps that didn't go exactly as planned, as well as a few "shortcuts" to reduce the time and effort required for the upgrade.
Here is the checklist I used from the TFS installation guide (In-Place or Migration Upgrade of Team Foundation Server on One or More Servers), along with my comments for each task. Note that in my next post, I'll provide the detailed steps for installing TFS 2010 (and SharePoint Server 2010) and upgrading a previous TFS 2008 (and WSS v3) configuration.
|Check for the latest installation guide.||The version of the installation guide that I used was last updated: March 29, 2010 (TFSInstall-3292010.chm).|
|Back up your data.|
I performed full backups of all "user" databases as well as a backup of the TfsWarehouse OLAP database.
I also ensured that I had a backup of the encryption key for SQL Server Reporting Services.
|Check for supported hardware and software.|
Note that TFS 2008 supported x64 on the data-tier but not on the application-tier. Consequently, when I built out my TFS 2008 environment, I used Windows Server 2008 x86 edition.
However, SharePoint Server 2010 is x64 only and therefore cannot be installed on Windows Server 2008 x86 edition. Consequently, in order to upgrade to SharePoint Server 2010, I rebuilt the application-tier using Windows Server 2008 R2 (which, like SharePoint Server 2010, is only available in x64).
Note that there is a known issue with Windows Server 2008 R2 that may effect TFS (see KB 981898). So far, I haven't experienced that issue, but if I do, I'll install the QFE to resolve the issue.
|Check for required permissions and user accounts.||I am using different service accounts for SQL Server, TFS, and SharePoint Server:|
|Check for supported environment settings.|
The functional level of my Active Directory domain (TECHTOOLBOX) is Windows Server 2008 mode.
I ensured the firewall ports for SQL Server were configured as necessary.
|Set up Internet Information Services (IIS).|
To reduce the time and effort required for the upgrade, I relied on the installation of SharePoint Server 2010 to install and configure IIS.
Note that SharePoint Server 2010 installs all of the role services required for TFS 2010 (and more).
Set up SQL Server.
Set up Reporting.
I installed SQL Server 2008 SP1 CU2 (with the update for KB 976761) on the backend database server (BEAST), since this is required by SharePoint Server 2010.
I also deleted the following obsolete SharePoint databases (since I created a new farm with SharePoint Server 2010):
Note that I deferred the setup of Reporting Services until after I had installed SharePoint Server 2010.
|Verify SQL Server.|
|Prepare Portal Server.|
Note that I had previously upgraded my TFS instance from WSS v2 to WSS v3.
To upgrade my TFS projects to SharePoint Server 2010, I performed a "clean install" and then attached the content database with the existing TFS project sites.

|Team Foundation Server Administrator Fills out Worksheet.|
In my environment, the "TFS Administrator" and the "SharePoint Administrator" are one and the same (i.e. me).
Refer to the "planning" section in my next blog post for specific details on my environment.
|Install and provision SharePoint Products.|
I installed SharePoint Server 2010 using the following TechNet article as a guide:
Deploy a single server with SQL Server (SharePoint Server 2010)
(more detail provided in my next blog post)
|Configure Microsoft Office SharePoint Server 2007.|
Jon Tsao has written a helpful blog post with details on how to configure SharePoint Server 2010 for TFS dashboards:
Configuring SharePoint Server 2010 for Dashboard Compatibility with TFS 2010
It's a little out-of-date (due to changes in SharePoint Server 2010 RTM from Beta 2), but once I found the links to configure Excel Services and the Secure Store Service, I was able to complete the configuration.
Unfortunately, my configuration is a little different from the configuration Jon used and subsequently revealed (what I believe to be) a bug in SharePoint Server 2010 with Excel Services. Refer to the following post for more details:
"The workbook cannot be opened" Error with SharePoint Server 2010 (and TFS 2010)
|Install and Configure Extensions.||I skipped this step because in my environment SharePoint Server 2010 is installed on the same server as TFS.|
|Administrator for SharePoint Products Fills out Worksheet.||Refer to the "planning" section in next blog post for specific details on my environment.|
|Verify local SharePoint Products.||As instructed in the installation guide, I added the TFS service account to the SharePoint Farm Administrators group.|
|Uninstall the previous version of Team Foundation Server.||Since I installed TFS 2010 on a new server (VM), I didn't have to uninstall the previous version.|
|Restore your data.|
When restoring data from the Production environment to the Test environment to perform a test of the upgrade process, I used SQL Server Management Studio to add permissions for the corresponding test accounts.
For example, I added TECHTOOLBOX\svc-tfs-test to the corresponding TFS databases and gave it the same permissions as TECHTOOLBOX\svc-tfs. Similarly, I added TECHTOOLBOX\CYCLOPS-TEST$ and give it the same permissions as TECHTOOLBOX\CYCLOPS$ (to grant acceess to services configured to run as NT AUTHORITY\NETWORK SERVICE).
I used the SharePoint Mount-SPContentDatabase cmdlet to attach the content database containing the TFS project sites and discovered a few issues with the upgraded TFS sites (more detail provided in my next blog post).
|Set up Team Foundation Server.|
The only option I selected for the application-tier was Team Foundation Server.
You do not need to select the option for Extensions for SharePoint Products and Technologies if SharePoint Server 2010 is installed on the same server as TFS.
|Final configuration of Microsoft Office SharePoint Server 2007.|
In addition to configuring the enterprise application definition, I also had to add the service account used for Excel Services to the SharePoint content databases for the TFS Web application.
This is described in more detail in my next two blog posts.
Upgrading VSTS 2008 Clients for TFS 2010
Here's something I didn't see mentioned anywhere in the TFS installation guide...
If you need to access TFS 2010 from a VSTS 2008 client (for example, to continue to use the source control integration features in Expression Web 3), you must download and install an update:
Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 (Installer)
Refer to KB 974558 for more information on the compatibility update.
Upgrading Team Foundation Build
Earlier I stated that I use a dual server configuration for TFS, but that's not entirely correct. There is actually a third server (DAZZLER) in my environment that performs TFS builds.
However, the only interesting part about the build server upgrade was that I had to increase the memory on that VM from 512 MB to 1024 MB to resolve a blocking "system check" issue when configuring the Team Foundation Build Service.
I also chose to just "bite the bullet" and install the full Visual Studio 2010 on my build server. Previously I just installed the minimum SDKs necessary to perform a build. However, the warnings from my build server about not being able to run my unit tests as part of the official build have finally pushed me to the point of installing Visual Studio instead.
Details for Upgrade Process
As mentioned throughout this post, I'll provide details about the installation, configuration, and upgrade of TFS 2010 and SharePoint Server 2010 in my next blog post.
