Hi Masha, I assume you are using the GoodData Platform and not the Cloud version. The main idea behind having staging and test domains is to make sure that your
LCM is ready to roll out the final changes to your production domain, but this will depend enterily on your setup. If you don’t have LCM configured, you can of course test any changes manually, for example, by cloning a production workspace to the test environment. LCM is available as an addon to Growth customers and included in the Enterprise tier.
