What is typically the first step in planning an upgrade to ensure compatibility?

• A. Review compatibility of the current environment with the new version
• B. Start upgrade without testing
• C. Immediately upgrade all sensors
• D. Change credentials

Answer: (A)

The first step in planning an upgrade is to review compatibility between the current environment and the new version. This check reveals whether hardware, operating systems, databases, Tanium components (server, console, modules), and network requirements meet the new version’s prerequisites. It also uncovers any necessary patches, module updates, or endpoint considerations so you know exactly what needs to be updated before or after the upgrade. This upfront assessment shapes the entire plan: it defines testing scope, required downtime, rollback procedures, and resource needs, and it helps ensure integrations and configurations will still work after the upgrade. Skipping this review invites blockers and surprises during the upgrade, which can lead to longer outages or partial deployments. Actions like starting the upgrade without testing, mass-upgrading sensors without confirming compatibility, or changing credentials don’t address whether the environment will support the new version and can introduce new risks.
