How to track known problems, iFixes, and Fixpacks
The original post emphasizes that support content evolves over time. Use IBM support resources as an ongoing process, not a one-time check.
- Search the known-problems page for release-specific issues and workarounds.
- Use the IBM support portal to navigate to product downloads.
- Review iFix and Fixpack entries before applying changes.
- Record which fixes are applied in each environment for traceability.

Best practices for maintaining legacy ClearCase releases
- Always validate platform compatibility before any upgrade activity.
- Use backups and rollback planning for every production change window.
- Treat known-problem searches as part of release readiness, not only incident response.
- Apply iFixes and Fixpacks only after reviewing applicability and dependencies.
- Keep an internal runbook with exact versions, host details, and applied fixes.
