I'm working on migrating our site to a different server. I need to do some testing on the new server while keeping the production site live. The problem is that the test server continues to run all the scheduled jobs and recurring contributions. I read about changing the environment (https://docs.civicrm.org/sysadmin/en/latest/misc/staging-production/#changing-your-environment), but that doesn't clearly state what actually gets disabled (besides mail jobs).
What is the best way to ensure that my test server has all that stuff disabled? I have several sites running on the server and need to do this from the command line.
