Delete a Team Project Collection

You can delete team project collections that are no longer being used in your deployment of Visual Studio Team Foundation Server 2012 (TFS). By deleting a collection, you ensure that users do not accidentally connect to it and work on projects within that collection, and you help simplify your deployment. Additionally, in rare cases, creation of team project collections fails or the database becomes unusable. In those cases, deleting the faulty collection also helps you maintain your deployment.

To delete a collection, you must first detach it from TFS. However, if you detach a collection, you do not delete the database for the collection from SQL Server. To truly delete a collection, you must then manually delete the database for the collection from the SQL Server instance that hosts the collection database. Similarly, if you detach a collection, you do not delete the SharePoint site collection that hosted the team project portals for projects in that collection. To delete those portals, you must also delete the site collection that supported that collection.

Important noteImportant

Ideally, each site collection supports only one team project collection, but it is possible for more than one collection to use the same site collection. You should verify that the site collection is not used by any other team project collection or for any other purpose before you delete the site collection.

You do not need to delete the database or the site collection, but the collection will not be truly deleted until you complete these steps. If you are deleting a collection for performance or space considerations, you should consider manually deleting the database from SQL Server and the site collection from SharePoint Products after you detach the collection.


You can delete a team project collection at a command prompt by using the TFSConfig Collection command. Unlike deleting a collection from the administration console, when you use the TFSConfig Collection tool, you permanently remove any chance of reattaching the collection database. For more information, see Collection Command.

Required Permissions

To perform the following procedures, you must be a member of the following groups:

  • a member of the Administrators security group on the server or servers that are running the administration console for Team Foundation

  • a member of the sysadmin group on the server or servers that are running the instance of SQL Server that hosts the databases for TFS

  • a member of the Farm Administrators group for the farm from which you are deleting the site collection, if your deployment uses SharePoint Products

For more information, see Team Foundation Server Permissions.
