Fix locally copied/added TFS folder so it is a Branch with Ancestry

Question

1. Copy folders between Team Projects LOCALLY (e.g. xcopy D:\foo\TeamProjectA\Blah D:\foo\TeamProjectB\Blah)
2. Add D:\foo\TeamProjectB\Blah to $/TeamProjectB.
3. Make $/TeamProjectA/Blah a Branch - does not have hierarchy.
4. Make $/TeamProjectB/Blah a Branch - does not have hierarchy.

How do I set the parent of TeamProjecB/Blah to TeamProjectA/Blah?

*EDIT * 2010-12-31 What about editing the DB directly?

Answer 1

That is not possible. You need to do a baseless merge if you want to achieve a merge between the two. But the branch relationship cannot be set.
