We are planning to build a custom solution for a 1000 business users on Jira Core. They are clinical background and may not have prior experience with Jira. There is a requirement for a 'Training' instance or environment that needs to be separate from a Dev/QA/Prod environment so that is remains stable for training purpose. A demo environment may work as well.
Is there an option to setup a training instance/environment for a 1000 business users.
