Raising the Rational® ClearQuest® feature
level and metaschema version can take several hours. The process changes the
schema repository and all associated user databases. Typically, new tables
are added to all databases, and new columns might be added to existing tables.
As part of upgrading the
Rational ClearQuest feature
level, perform the upgrade on a test system first, and perform it again on
production databases. At a high level, the process is as follows:
- Prepare your environment.
- Back up all of your databases.
- Create a test bed based on production databases.
- Upgrade the test bed and validate that the upgrade was successful.
- Create new databases for the production system.
- Upgrade the production databases and verify that the upgrade was successful.
Note: If you are using Oracle databases with the LONG datatype, you cannot
combine a feature level upgrade with a LONG to CLOB conversion. Performing
these tasks in the same operation can corrupt data.
