I’ve recently merged a series of changes from my Foundry Branch. Is it possible to undo the merge or unmerge those changes?

Currently, there is not a consolidated solution to undo a merge via the branching app. In som applications, you have the ability to revert the resource to a previous version. So you could “undo” your merge by iterativelty reverting the versions.

**Workshop** :  
Within Workshop, clicking the version underneath the module name provides the Versions dialog were you can select the desired version to revert to:

**Pipeline Builder:**  
Within Pipeline Builder, on the history tab, you can select the desired version to reset to:

**Ontology Manager:**  
Ontology Manager does not provide a one-click revert option at this time, but you can in the History tab to identify the changes and manually revert by making the reverse changes.
