Low – Medium
If you use JIRA in a non-mission critical environment, depending on your specific installation details, you use either the safe (no downtime) or manual method to upgrade.
If you are upgrading from JIRA 4.3.0 or later, you also have the option to use the upgrade capabilities built into the installer to perform a rapid upgrade of your existing JIRA installation - this method is the fastest way to upgrade - however due to its in-place upgrade method, having recent backups is crucial for this option.
