Is there any way to auto merge a TFS baseless merge?

This is TFS 2008.

The trunk was renamed and we now need to merge a great^6 grand child of the trunk back into it. We are only able to do a baseless merge. When a baseless merge was done there were 13,000 conflicts. Auto-merge was then tried and it only reduced the conflicts by 1,000. The majority of these files are identical. I was w开发者_JAVA百科ondering if there was any way to get TFS or visual studio to do a more aggressive auto merge based on file content.

If this is not an option through TFS any thoughts on how to do something similar through a powershell script or the TFS SDK would be greatly appreciated.

Thanks.

Rename the trunk back to its original name, and the merge will cease to be "baseless."

Yes, I hear you, that is beyond stupid but it works. I don't make this stuff up.
