TFS - Is it possible to rollback a changeset committed before the branching?

Question

Suppose I Branch Solution-A, changeset 10 into Solution-B.

Later on, I realize Solution-B should not have changeset 7 in it.

Is there a way to rollback changeset 7 just from Solution B without harming solution A?

Whenever I use tf rollback, all the pending changes go to Solution-A.

Thanks in advance !

Answer 1

You have to rollback the changeset that has the merges to solution b, and then reapply the merge without changeset 7.

Answer 2

I know this is an old question, but this may help anybody who has the same problem. Especially when you need to rollback a changeset, which was checked in long ago on another branch.

Update WORKSPACE_ROOT and TFS_BRANCH_ROOT in the following batch file. Name it e.g. RollbackMigrate.cmd and run it always from the workspace root.

This batch file will:

1. Parse arguments - only one argument is the change set number
2. Find the name of current workspace and it's path on TFS
3. Find the TFS source path for migration
4. Map the source into current workspace
5. Rollback the change set
6. Create shelve set and undo check out
7. Remove the temporary mapping
8. Unshelve the previously created shelve set and migrate it
   • you just need to auto merge the shelveset in a new window
9. Delete the temporary shelve set
10. Checkin
    • you just need to update the comment, notes and work item link

Answer 3

I recommend using the TFPT.exe which comes with the power tools pack: http://visualstudiogallery.msdn.microsoft.com/c255a1e4-04ba-4f68-8f4e-cd473d6b971f/

High level overview:

1. From the workspace mapping of Solution-B rollback the changeset
2. Commit the change for the workspace mapping in Solution-B

Commands:

1. c:\workspace\mapping\to\solution\b> tfpt rollback /changeset:7
2. c:\workspace\mapping\to\solution\b> tf commit

Answer 4

Finally I did something like below.

1. Rollback changeset 7 on Solution-A and checkin. This will create changeset 11 on Solution-A
2. Merge the changeset 11 to Solution-B branch
3. Rollback changes 11 on Solution-A branch and checkin which will create changeset 12 on Solution-A

In future merges to Solution-B from Solution-A skip merging changeset 12.
