You upgrade from a previous version of Team Foundation Server to Visual Studio Team Foundation Server 2010.

The upgraded team project collection is named UpgradedCollection. You need to permanently move a team project named MyApp from UpgradedCollection to a new team project collection.
What should you do?

A.
Prepare a clone of the UpgradedCollection by running the TFSConfig.exe /prepareClone command.

B.
Split the UpgradedCollection. In the Team Foundation Server Administration Console, attach the new team project collection, using a new name. Then delete the unnecessary team projects in both the collections.

C.
Move the UpgradedCollection database files to a new data tier server. Then in Microsoft SQL Server Management Studio, attach the UpgradedCollection database to the new Microsoft SQL Server server instance.

D.
In Microsoft SQL Server Management Studio, copy and rename the UpgradedCollection database files. Attach the original database and the copy of the database files to the same Team Foundation Server server instance.
