If JIRA is a tomcat/Java application, I don't understand why a complete reinstall, backup, and import would be needed when moving the application from one server to another server.
Why is is not possible to just copy all the files and clone the database? (of course, updating the database configuration and licenses on the new server)
Is JIRA designed to break if moved? This is not typical behavior for a JavaEE application.
thanks,
Kevin
