Hi Team, I have installed the DEA tool for testing the upgraded environment. About the environment: I have installed SQL Server 2017 Developer edition and restored the production database from SQL server 2014 on it. On the same server I configured the Distributed Controller, distributed client and also installed the DEA tool. I can run the DEA tool successfully to capture the trace on Production server (SQL server 2014) and replay them on A (SQL server 2014 Dev server) and B (SQL server 2017 Dev server). As per the process, before I start the capture I take the transactional log backup from the production database and then restore it on both A and B dev servers and then start the replay. So far everything looks fine, except the pass% which does not increase more than 32% on both A and B Dev servers, due to which I think the analysis seems to be blank with no graphs or recommendations. Issue : I couldn’t get enough information on how to get pass rate above 90%. I tried doing everything but couldn't try to match the hardware requirements of production and development environment as mentioned in microsoft page https://docs.microsoft.com/en-us/sql/dea/database-experimentation-assistant-get-started?view=sql-server-ver15. Can I get some help to achieve the pass rate above 90%.
