How to do it...

Upgrade your Jira system with the installer using the following steps:

1. Take your current Jira offline, for example, by running the stop-jira.bat script.
2. Back up the Jira database with its native backup utility.
3. Launch the installer and select the Upgrade an existing JIRA installation option.
4. Now, select the directory where the current Jira is installed:

1. Check the backup JIRA home directory option and click on the Next button.

1. Review the Upgrade checklist and click on the Upgrade button:

1. Wait for the installer to complete the upgrade process. Once the upgrade is complete, the installer will automatically launch Jira.
2. Update any add-ons once Jira starts successfully.

The installer will detect and provide you with a list of customized files in the JIRA_INSTALL directory, which you will need to copy manually after the upgrade.
