Copy SSRS reports to another server

I am new to SSRS and I have been tasked to copy the SSRS reports(from PROD) to another Server(QA). I found many documentations that show how to migrate the reports by Restoring ReportServer, ReportServerTempDB and encryption key. I just want to confirm. After doing above, my main environment(prod) will remain intact and operational?Please confirm. I'm creating a QA environment that I am copying from PROD and I cannot afford for anything to happen to PROD.
