Reset your QA environment to mimic your Production environment as closely as possible, being sure to use the same hardware and software versions used in the Production environment.
Specifically, you want to replicate the following in your Production environment:
Platform, including the following:
Application server
Database server
Gateway server
Web Server (optional component)
Common client machine with the corporate image and same browser
Waveset product version
Waveset application configurations and customizations
Database tables and actual data, including data values and the volume of data found in the Production environment
Resources and other integrated applications
Configure resources and other integrated applications in the QA environment to have the same general configuration as those used in the Production environment. For example, replicate Active Directory domains, organizations, groups, numbers, and the format of users from Production to the QA environment.
Also, be sure to configure integrated applications the same way in both the QA environment and the production environment, and make sure that these applications contain a copy of recent production data or very similar data.
