You must install Rational solution for Collaborative Lifecycle Management before you install the Rational Adapter for Git. When you install the Git adapter, you select an existing package group so that the Git adapter installs into an existing Jazz Team Server installation directory.
To install Rational solution for Collaborative Lifecycle Management see, Installing by using Installation Manager.
If you plan to upgrade Rational solution for Collaborative Lifecycle Management, you must migrate the Git adapter, see Migrating the adapter to an upgrade installation of CLM.
