Analyze the collected data to pinpoint performance bottlenecks. Common areas include slow database queries, high CPU usage, or network latency.

Based on my experience, unexpected performance issues in legacy migrations often stem from overlooked dependencies or inadequate testing in simulated environments. A key strategy is preemptive performance testing with tools like LoadRunner or JMeter in conditions that mimic real-world scenarios. Additionally, I recommend segmenting the migration into smaller, iterative phases. This approach isolates issues early without derailing the overall project. Finally, establish a rollback plan to minimize downtime. Proactively engaging with stakeholders ensures alignment and trust while resolving challenges. Focus on continuous improvement during migration for long-term system health.

Migrating Legacy Systems? Address Performance Issues Effectively: Conduct thorough assessments: Review logs and metrics to identify bottlenecks. Optimize configurations: Adjust settings and parameters for improved performance. Implement monitoring tools: Use real-time tools to detect and resolve issues quickly.

How can you be certain it's a performance issue? Do you have a baseline for comparison, or is it just speculation due to recent changes or rumours?
