A company is migrating its monitoring platform from Dynatrace to Instana across 800 production hosts. The operations team has a hard requirement that there must be no monitoring blackout during the migration period. Which migration planning approach best ensures continuous observability throughout the transition?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Running both monitoring agents in parallel during the transition is the safest migration strategy, allowing the team to validate that Instana captures equivalent observability coverage, tune sensor configurations, and recreate critical dashboards and alerts before removing the incumbent tool. Both Dynatrace and Instana agents can typically coexist on the same host without conflict, sharing system resources. Removing Dynatrace before validating Instana coverage creates the monitoring blackout that the requirement explicitly prohibits.

Full Explanation
Running both monitoring agents in parallel during the transition is the safest migration strategy, allowing the team to validate that Instana captures equivalent observability coverage, tune sensor configurations, and recreate critical dashboards and alerts before removing the incumbent tool. Both Dynatrace and Instana agents can typically coexist on the same host without conflict, sharing system resources. Removing Dynatrace before validating Instana coverage creates the monitoring blackout that the requirement explicitly prohibits. The correct answer is 'Run Dynatrace and Instana agents concurrently on all hosts during a parallel operation period, validate Instana coverage completeness, then decommission Dynatrace'. The incorrect options — 'Immediately uninstall all Dynatrace OneAgents before deploying Instana agents to prevent any resource conflicts on hosts', 'Export all Dynatrace dashboards and alerting thresholds directly into Instana format before beginning any agent migration work', 'Use the built-in Instana migration toolkit to automatically convert Dynatrace OneAgent configuration files to Instana agent configuration' — are wrong because they do not align with IBM Instana's architecture or recommended practices for this scenario. Understanding this concept is essential for the Domain 5: Planning domain of the IBM Instana Observability certification.
