There are several different ways to upgrade JIRA, and the method you choose to use depends on which version of JIRA you use and the type of environment you use it in. Use this table to determine which steps to follow to complete your JIRA upgrade:

This method is recommended for enterprise environments where extended or unplanned downtime might negatively impact the business.

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.
