Many of you might’ve come across a situation wherein you’re planning for a SQL Server upgrade, and at the same time, skeptical of the performance/throughout that you’re going to get from this upgraded version of database.
Database Experimentation Assistant (DEA) is a new A/B testing solution for SQL Server upgrades. It will assist in evaluating a targeted version of SQL for a given workload. Customers who are upgrading from previous SQL Server versions (SQL Server 2005 and above) to any new version of the SQL Server will be able to use these analysis metrics provided, such as queries that have compatibility errors, degraded queries, query plans, and other workload comparison data, to help them build higher confidence, making it a successful upgrade experience.
Current available version (As of this writing) is 2.1.51169.2
Supported sources and target versions
Source: SQL Server 2005 and above
Target: SQL Server 2005 and above
Analysis: SQL Server 2008 and above
