Upgrading Jira applications
There are several 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:
If you need to move Jira to a new server, or use it in a new environment that has a different operating system, different database type, or different location of attachment or index files, follow the instructions for Migrating Jira to another server.
|Upgrade method||Is this right for you?|
Upgrade Jira using an installer
This method includes the use of a typical installation wizard that will guide you through all the stages of upgrading Jira.
Upgrade Jira manually from a zip or archive file
|This method includes downloading Jira files compressed into a .zip or .tar.gz package, and extracting them into the chosen location. It doesn’t include a typical upgrade (as you'll extract an almost-ready Jira instance), and so is much faster.|
Upgrade Jira with a fallback method
|This method allows you to safely roll back to your previous Jira version if the upgrade takes longer than expected, or if you encounter any issues. It requires that you set up a proxy server to have a quick way of redirecting your users either to the existing or to the new instance of Jira.|
Upgrade Jira Data Center on a single node
It's the same as a Server upgrade:
|If you have deployed Jira Data Center on a single node, without setting up a cluster, you can upgrade it just like you would a Server installation, using the installer or archive file.|
Upgrade Jira Data Center in a cluster
If you have deployed Jira Data Center in a cluster, we'll show you the quickest way to upgrade it by using the archive file.
Upgrade Jira Data Center with zero downtime
Upgrade with zero downtime is a special method available for a Jira Data Center cluster. It introduces the upgrade mode that allows your nodes to work on different Jira versions while you upgrade them one by one. During the upgrade, Jira remains fully functional and open to your users.
