TFS Integration with Sharepoint for existing TFS projects

I recently got a question on this and it seemed useful enough for a post to my blog.  They installed TFS without initially integrating with SharePoint. They had many projects that don't contain SharePoint portals. Then they integrated SharePoint with TFS and can only set up a SharePoint portal with new projects created. Is there any way to create a SharePoint portal for existing TFS projects? Are there any workarounds to achieve this goal?

The answer is yes and yes, and there are a few options to get this done:

Depending on how many you have to do there are two basic approaches that I've used. To begin you need to be in the Project Administrators group or have the View Collection-Level Information and Edit Collection-Level Information permissions set to Allow.

Manual Method, good if you just have a few. Follow the instructions one MSDN here: http://msdn.microsoft.com/en-us/library/dd386320.aspx . Basic steps are:

1.In Team Explorer, right-click the name of the project, point to Team Project Settings, and then click Portal Settings.
2.On the Project Portal tab, select the Enable project portal check box.
3.Click Use this SharePoint site, and then click Configure URL.
4.In the Web application list, click a SharePoint Web application.
5.In Relative site path, type the relative path of an existing SharePoint site.As you type the path, it appears at the end of the value in URL.
6.In URL, click the link, verify that the path is correct, and then click OK.
7.If you want this SharePoint site to show data for this project, select the Reports and dashboards refer to data for this team project check box.
8.Click OK.

Scripting with File.BatchNewTeamProject, more complex but creates the reports as well and good if you have a bunch to do at once. I did a few hundred in fairly short order using this method. Follow the detailed steps here http://msdn.microsoft.com/en-us/library/ff462695.aspx .
