Conceptually, a merge branches operation has four steps: 1  Developer selects changes in the origin. 2  Source control tool applies some changes automatically to the target. 3  Developer reviews the results and resolves any conflicts.  Commit.
1 Structure your branch trees so that you only need to merge along the hierarchy (up and down the branch tree) rather than across the hierarchy. 2  Branching across the hierarchy requires that you use a baseless merge, which requires more manual conflict resolution.
