What sequence of steps is typically included in an upgrade plan for Tanium core and modules?

• A. Skip backups, upgrade all at once, and notify users after.
• B. Only upgrade modules, ignore core.
• C. Assess compatibility, backup, staging/QA, upgrade in sequence, verify module compatibility, validate data integrity, train users, debrief.
• D. Test in production with live data.

Answer: (C)

A thorough upgrade plan for Tanium upgrades centers on managing dependencies, protecting data, validating changes in a safe environment, and preparing people for the new state. Start by assessing compatibility between the Tanium core and its modules so you know which versions work together and what dependencies exist. Next, take backups of configurations and critical data; having a rollback point is essential if anything doesn’t go as expected. Use a staging or QA environment to test the upgrade steps with production-like data and workloads, catching issues before touching live systems. Upgrade in sequence by updating the core first, then the modules, and afterward verify that each module remains compatible with the new core version and continues to function as intended. Validate data integrity to ensure that data collection, storage, and reporting are accurate after the upgrade. Train users on any new features or changes, so adoption is smooth and support requests don’t spike. Finally, hold a debrief to capture what worked, what didn’t, and update runbooks and change-management processes for future upgrades. This approach is best because it reduces risk, protects data, and ensures that interdependent components stay in sync, while also preparing the organization for a successful transition. Skipping backups, upgrading everything at once, focusing only on modules, or testing directly in production with live data would expose the environment to unnecessary risk and potential downtime.
