Working with Patches

A deployment package that cannot be installed on its own, but has to be installed on top of another package, is referred to as patch package or simply patch. A sequence of patches is referred to as patch chain. When deploying a patch to a target environment, the system will deploy all patches that are required to bring the currently installed application to the selected patch package.

Important! The actions that you can perform depend on your folder permissions. See: Assigning Release Automation Permissions.
