Install and configure the Serena Common Tomcat Web server and Serena Release Control as usual. If you have already done this, you do not need to do this again!
When you are finished, publish and redeploy the process apps. As you deploy, verify that the endpoints of the process application destinations are pointing to the port number you specified during the installation rather than the default port number of 9095. If they are not, update them as needed before deploying.
