Changing a database association to a different schema

After a user database is associated with a schema, you cannot apply a new schema to the database. You can upgrade a database only with newer versions of the same schema.

For example, if a user database uses version 1 of the DefectTracking schema, you can upgrade that database to version 2 of the DefectTracking schema, but you cannot upgrade to the Enterprise schema.

However, you can move the data in an existing user database to a new database that is associated with a new schema. To do so, you must create a new database and associate it with the new schema. Then, you can use Rational® ClearQuest® tools to export the data from the old database and import it into the new one.

You can use the command-line utility, cqload, and the import and export functions, to copy all or part of a schema into another schema repository. For more information, see Importing and exporting data and the command line reference pages.
