As the Jira installer is only available for standalone installations on Windows and Linux, we will run you through the installer on Windows in this recipe:

• Check the upgrade notes for any special instructions as well as the target Jira version to make sure you can perform a direct upgrade.
• Make sure you have a valid Jira license.
• Verify whether your current host environment is compatible with the target Jira version. This includes the Java version, database, and OS.
• Verify whether your operating environment is compatible with the target's Jira version, specifically, the browser requirements.
• Make sure that the add-ons you are using are compatible with the new version of Jira.
• Download the installer binary for your target Jira version.
