I want to install a module in enterprise version 13.0. Before installing I want to check it being if it fails and the system crushes the entire system will be interrupted. 

I have duplicated the production database, and planned to test the new module in the duplicated database as a test and if it works fine i will install it in the production database. 

The problem is how can I run both the production and test environment at the same time ? The production using port no 8069 and the test with other port no such as 8081 ?

For the case of community edition, it can be installed anywhere and tested in different environment, but for the enterprise case I face difficulty to test in non-production environment. Would you give me an advise ? 

Kind regard
