Chapter 6. Multiple branches in Decision Central
Multiple branches support in Decision Central provides the ability to create a new branch based on an existing one, including all of its assets. All new, imported, and sample projects open in the default master branch. You can create as many branches as you need and can work on multiple branches interchangeably without impacting the original project on the master branch.
Red Hat Decision Manager 7.2 includes support for persisting branches, which means that Decision Central remembers the last branch used and will open in that branch when you log back in.
6.1. Creating branches
You can create new branches in Decision Central and name them whatever you like. Initially, you will only have the default master branch. When you create a new branch for a project, you are making a copy of the selected branch. You can make changes to the project on the new branch without impacting the original master branch version.
