How to Remove a Branch from the Middle of the Hierarchy?

I have a Team Project created with the "Standard" branch pattern from the ALM Rangers' Branching guidance:

Standard Branch Hierarchy

After creating it, I found that I only really needed the "Basic" pattern. That is, I don't need the "Service Pack" branch.

Is there a way for me to remove the "Service Pack" branch and "heal" the hierarchy so that "Release" is under "Main" in the hierarchy? Right now, every changeset in the "Service Pack" hierarchy has a corresponding changeset in the "Release" hierarchy, as "Service Pack" has just been in the way.

The simplest solution is to not remove or reparent.

The service pack branch is the "service pack branch" in name only. Delete the "release" branch and rename the "service pack branch" to "release".

Well I don't know about old version of TFS, but at least in TFS2012/VS2013, you can do:

  1. A Baseless merge from Main -> Release
  2. Source Control Explorer > Branching and Merging > Reparent, choose Main (the new parent)

Done!

The following worked for me in a similar scenario

tf merge /baseless /recursive /noprompt /discard $/TFS/Path/To/Release $/TFS/Path/To/Main

then:

  • delete "Service Pack" branch
  • check-in "Main" and "Service Pack"

now you can do normal GUI merges from "Release" to "Main"

NOTE: As many people already have mentioned, be careful with baseless merges they can bite you in the jewels later on down the line when abused.

Branches in TFS are unfortunately old-fashioned (or, "Dinosaur-like" if you ask Torvalds ;) in that once created, the structure is set and cannot be changed. I believe you will have to create a new Release Branch directly below the Main, and then perform a baseless merge from the old Release branch to the new. I think you should use the /noprompt parameter to the merge command to stop the "Resolve Conflicts" dialog to show.

This will give you more conflicts than really needed, since TFS won't know what ancestor to use. But since you will want to take all from the original Release branch, you can use the command tf resolve /recursive /auto:TakeTheirs to tell TFS to always take the changes in the source branch.

After that, you should be able to remove the old branch tree.

Complicated, but not impossible.
