After you check in a schema, you can upgrade the user databases
to use the newer schema version. You do not have to upgrade these databases
immediately, but the changes to the schema are not available until you do.
Upgrading a user database is an irreversible process. Before you apply
schema changes, back up the user database. Also, immediately before you apply
schema changes, verify that no users are logged in to the database. The upgrade
operation fails if users are connected to the user database. Users cannot
log in during the upgrade process, but they cannot be disconnected.
When a user
database is associated with a specific schema version, you can apply only
newer versions of the same schema to that database. You cannot apply earlier
versions or a different schema.
For more information about databases,
see the online Help for Administering Rational® ClearQuest®.
