Duplicating change to choose a set of changes made in one branch and apply them to another branch. You can select specific files with changes to duplicate or you can duplicate changes based on a changelist, issue, or label. Specific changes can be duplicated to any branch in the same branch tree without promoting changes to a common parent first.
For example, Steve makes a change in his workspace branch that fixes an issue related to two different products. He can duplicate the changes in files attached to the issue to each product's baseline branch without merging all other changes he made in his workspace branch. After duplicating, he can track the changes to make sure the changes are included in all branches that contain files attached to the related issue.
Note: Only changes that affect the file version, such as changes to file contents or file addition and removal, can be duplicated.
