How to Clone or copy Production Jira Service Management Cloud project/instance to Sandbox

[Amanda Wernicke]

My goal is to test an integration between ServiceNow and several different Jira Software (Cloud) and Jira Service Desk (Cloud) projects. Our Sandbox was just recently set up and only has a generic test project. To have an effective Sandbox test, we need to have the same project workflows and settings as we have in Production.

I've searched in documentation and community and haven't been able to find anything about how to copy/clone from Production into Sandbox besides  https://community.atlassian.com/t5/Jira-questions/Cloning-production-into-test-staging-environments/qaq-p/309356 

This information is about a script to automate the repetitive boring task, but right now I need a set of instructions to do this task one time. Or someone to provide me a script to run with instructions how to do it. I appreciate any help you can provide.
