Pre-upgrade planning tool

Upgrading Confluence or Jira? You can instantly create a tailored upgrade plan using the pre-upgrade planning tool, located in your application's admin console.

We recommend a version to upgrade to, run pre-upgrade checks, and provide you with a custom upgrade guide with step-by-step instructions.

Prerequisites

To access the upgrade planning tool, you'll need the Troubleshooting and Support tools app installed. This is bundled with your application, but you may need to update the app. Learn how to update apps.

Find the pre-upgrade planning tool

To access the tool, go to your application's admin console. You'll need to be logged in as an administrator to do this.

• For Confluence: Choose  > General Configuration > Plan your upgrade
• For Jira applications: Choose Administration ( ) > Applications > Plan your upgrade

Health checks

The pre-upgrade planning tool runs the health checks listed below, so you can identify and fix any issues before you upgrade. These checks are based on the supported platform requirements of the version you're upgrading to.

Health check	What does the check do?	Jira Server and Data Center	Confluence Server
Supported databases	Ensures your instance is using a supported database vendor and version.
License expiry	Ensures your software maintenance or subscription is active.
Java version and vendor	Ensures you're using a supported version of the JDK/JRE.
Collation check	Ensures your database is using the correct collation. Only runs if you're using MySQL or Microsoft SQL Server.		Confluence won't start with an incorrect collation

Files we check for modifications

As part of your upgrade plan, we check the following files in your current installation to see if they contain custom modifications. If any of these files have been modified, we prompt you to re-apply the change as part of the upgrade steps.

Confluence files

We check all files under <install-dir>/confluence

Jira files

We check all files located under:

• <install-dir>/atlassian-jira
• <install-dir>/bin/setenv.sh
• <install-dir>/conf/server.xml

Proxy considerations

To make sure the pre-upgrade planning tool shows the latest version data, your application needs to be able to access the following URL:

https://puds.prod.atl-paas.net/rest/v1/upgrade/info

If a connection can’t be established, for example if you’re using restrictive firewall or proxy server settings, the tool won’t be able to fetch any updates to version data, supported platforms or documentation.

In these cases, we recommend updating to the latest version of the Troubleshooting and Support tools plugin. This will ensure the content is current. You could also consider checking the relevant supported platforms page, or allowing access to the URL above.
