It will assist in evaluating a targeted version of SQL for a given workload. Customers upgrading from previous SQL server versions (starting 2005 and above) to any new version of the SQL server can use these analysis metrics provided by tool, such as queries that have compatibility errors, degraded queries, query plans, and other workload comparison data to build higher confidence and have a successful upgrade experience.<\/p>\n<h3>What Can I Do?<\/h3>\n<p>DEA offers the following capabilities for workload comparison analysis and reporting:<\/p>\n<ul>\n<li>Set up automated <strong>workload capture and replay<\/strong> of production database (using existing SQL server functionality Distributed Replay &amp; SQL tracing)<\/li>\n<li>Perform <strong>statistical analysis<\/strong> on traces collected using both old and new instances<\/li>\n<li>Visualize data through <strong>analysis report<\/strong> via rich user experience<\/li>\n<\/ul>\n<p>With DEA, you can:<\/p>\n<ul>\n<li>Capture Trace: you can automatically capture a production workload trace with only a few inputs.
