About the integration package
To install the base ClearCase integration with Rational ClearQuest requires that the Rational® ClearQuest® schema designer add the ClearCase® 1.0 package to an existing schema. The package accompanies the Rational ClearQuest product and supplies new stateless records to target record types. The Rational ClearQuest administrator then upgrades the Rational ClearQuest user database with the revised schema. Because you cannot remove a package after you add a package to a schema, the Rational ClearQuest documentation suggests that you use a test environment before you modify your production environment.
