The current setup is as follows:
There is a jira stage server running jira 7.x and it got an initial import from a full backup (from jira production that is running an old 6.x jira version as of now).
Now as development evolves on jira development it is important to be able to synchronize all project data (issues / comments / attachments) and users that were newly added to production to the jira development server.
What is the proposed way of handling that?
The plan is to move the jira development instance to production and replace current production server at some point.
Development of new features on the production server is not an option.
