To retain a copy of your branch, you can package the contents of a branch in a .jar file. Data instances that are tagged with the rulesets that are associated with the branch and history record are included in the package.
Click App > Branches.
Right-click the branch that you want to package and click Package. A browser window displays the progress of the packaging process.
If any rules in the branch rulesets are checked out, the latest version of the checked-in rule is included in the package.
