Step 2: Stop ILMT Services
- Before starting the upgrade, stop all ILMT services running on the server. This will ensure no conflicts or data corruption during the upgrade process.
- Confirm that no scans or report generation tasks are in progress to prevent interruptions.
Step 3: Apply the Upgrade
- Run the upgrade installer with administrator privileges.
- Follow the prompts to:
- Specify the installation directory.
- Connect to the existing database.
- Retain or overwrite previous configurations as required based on your organizational needs.
- Monitor the installation process for errors or warnings and resolve any issues immediately.
Step 4: Update the Product Catalog
- Download the latest ILMT product catalog from IBM’s support portal.
- Import the catalog into the upgraded ILMT instance to ensure accurate tracking of IBM software and compliance with current licensing rules.
Step 5: Restart ILMT Services
- Restart the ILMT application and related services, ensuring all components initialize correctly.
- Verify that the application launches successfully and that all services are operational without errors.
Step 6: Perform Post-Upgrade Validation
- Check the integrity of the database by running a test scan.
- Validate existing configurations, including scanning schedules, agent connections, and reporting templates.
- Generate a test report to confirm functionality and ensure data accuracy.
4. Best Practices During the Upgrade
To ensure a seamless upgrade process, follow these best practices:
a. Schedule Downtime
- Plan the upgrade during non-peak hours or maintenance windows to minimize disruptions to business operations.
- Inform end-users of potential temporary unavailability of reporting or compliance data.
b. Test in a Staging Environment
- If possible, replicate the production environment in a staging area to test the upgrade process and resolve issues before applying it to live systems.
c. Retain Historical Data
- Ensure that historical data, including past scans and compliance reports, is preserved during the upgrade process.
- Verify data integrity after the upgrade by comparing it with backups and pre-upgrade reports.
d. Document the Process
- Maintain detailed records of the upgrade steps, configurations, and any issues encountered.
- Update internal documentation to reflect changes introduced in the new ILMT version.
5. Common Challenges and Solutions
a. Compatibility Issues
- Problem: The new ILMT version may not support older hardware, databases, or virtualization platforms.
- Solution: Review the release notes and upgrade prerequisites before starting. Upgrade incompatible components if necessary.
b. Data Migration Errors
- Problem: Data loss or corruption during the upgrade process.
- Solution: Perform thorough backups and validate data integrity after the upgrade.
c. Service Downtime
- Problem: Prolonged downtime during the upgrade process.
- Solution: Schedule upgrades during low-usage periods and ensure adequate testing beforehand.
d. Configuration Loss
- Problem: Custom configurations and schedules may be overwritten during the upgrade.
- Solution: If needed, back up configuration files and reapply them after the upgrade.
6. Validating the Upgrade
After the upgrade, validation is essential to ensure the system operates correctly and meets organizational needs.
a. Run Full Scans
- Perform full scans of all monitored systems to ensure accurate data collection.
