You can't just move files around since Qlik has for each of them references in the Repository. There are a number of tools which can help you to achieve your scope. I suggest you to have a look to this page as starting point
Hi, I was testing something and was finally successful.
I have a virtual machine running with Qlik Sense server and made a copy of it and changed the machine name to be unique in the network. After some small changes in the repository DB and some other minor steps I was able to create a fully functioning System copy of a running PROD System in the same network ...
This would not fulfill my requirement. I want to have an _indepedant_ copy of the PROD system which will be used as TEST System later on. A multinode QS server is an integrated part of the PROD Environment, but I need to have it independant.
