Stress testing sql

captured some SQL events using the default replay template in one SQL server and like to replay them on a different SQL server under a different database name which is the same as the source database but is a week old
1. Since my ‘replay’ server has a different server name and a different database name, how can I instruct the profiler to run the replay using a different database name?
->You have to save trace in SQL Script format and change in QA all differences(database,etc.)
2. What are the requirements for me to run the replay successfully? For example, do I have to create the same SQL login names and/or SQL user names? What do I need to do?
->Yes you need to create logins, etc.
