Understanding the DevOps Code ClearCase integrations with Rational ClearQuest

There are two separate integrations with Rational® ClearQuest®:
  • The base ClearCase® integration with Rational ClearQuest
  • The UCM integration with Rational ClearQuest

The integrations associate one or more Rational ClearQuest user database records with one or more ClearCase versions, allowing you to use features of both ClearCase and Rational ClearQuest.

Note: The base ClearCase integration with Rational ClearQuest cannot be used with UCM projects.

In general, you should use the base ClearCase integration with Rational ClearQuest and the UCM integration with Rational ClearQuest separately, and avoid using a common Rational ClearQuest user database. However, it is possible for both integrations to use the same Rational ClearQuest user database. This can be useful if you are moving a project to UCM and have a substantial amount of information in a Rational ClearQuest user database that was created with the base ClearCase integration with Rational ClearQuest. You may want the new work in UCM to be reflected in new Rational ClearQuest records in the same Rational ClearQuest user database.

You should be aware of the considerations in managing the coexistence of the base ClearCase integration with Rational ClearQuest and the UCM integration with Rational ClearQuest.
