Distributed Replay feature helps you assess the impact of future SQL Server upgrades. Similar to SQL Server Profiler, you can use Distributed Replay to replay a captured trace against an upgraded test environment. Unlike SQL Server Profiler, Distributed Replay is not limited to replaying the workload from a single computer.
