Before you begin

Before you upgrade Confluence, there's a few questions you need to answer. 

Is manual the right upgrade method for you?	Tell me more... You can choose to upgrade using the installer, or manually using a zip or tar.gz file. In most cases the installer is the easiest way to upgrade your Confluence instance. You will need to upgrade manually if you are: moving to another operating system or file location as part of this upgrade. upgrading from Confluence 3.5 or earlier upgrading from Confluence 5.6 or earlier and previously used the EAR/WAR distribution to deploy Confluence into an existing application server.  performing a rolling upgrade, and you need to upgrade each node individually.
Are you eligible to upgrade?	Tell me more... To check if software maintenance is current for your license, go to Administration menu , then General Configuration. and select License Details on the left panel to make sure the license support period has not expired. Software maintenance: upgrade at any time during this period.  If your support period has expired, follow the prompts to renew your license and reapply it before upgrading.
Have our supported platforms changed?	Tell me more... Check the Supported Platforms page for the version of Confluence you are upgrading to. This will give you info on supported operating systems, databases and browsers. Good to know: If you need to upgrade Java, remember to update your JAVA_HOME variable to the new version. The Confluence installer includes Tomcat, so you won't need to upgrade it separately. If you need to upgrade your database, be sure to read the upgrade notes for the Confluence version you plan to upgrade to (and any in-between) to check for any database configuration changes that you may need to make.
Do you need to make changes to your environment?	Tell me more... Newer Confluence versions sometimes require changes to your environment, such as providing more memory or adjusting your reverse proxy settings. Good to know: We use Upgrade Notes to communicate changes that will impact you, such as: Changes to supported databases, memory requirements or other changes that will impact your environment. Features that have significantly changed or been removed in this release. Actions you may need to take in your instance or environment immediately after the upgrade. It's important to read the notes for the version you're upgrading to and those in-between. For example, if you are upgrading from 5.8 to 5.10 you should read the upgrade notes for 5.9 and 5.10.

Plan your upgrade

1. Determine your upgrade path

2. Complete the pre-upgrade checks

1. Check the Upgrade Notes for the version you plan to upgrade to (and any in between). 
     

2. Go to Administration menu , then General Configuration. > Plan your upgrade then select the version you want to upgrade to. This will run some pre-upgrade checks. 
    

3. Go to Administration menu , then General Configuration. > Troubleshooting and support tools to run the health check. 
   
   

   License expired?

   If the software maintenance period included in your license has expired you can keep using Confluence, but you'll need to renew before you can upgrade.

   Go to Administration menu , then General Configuration. > License Details and follow the prompts to renew your license.

   Database character encoding incorrect?

   Database character encoding must be set to UTF8 (or UTF8MB4 for MySQL databases, or AL32UTF8 for Oracle databases). You will not be able to upgrade to the current Confluence versions unless you have the correct character encoding.

     

4. Go to  Administration menu then Manage apps and scroll down to the Confluence Update Check to check the compatibility of your Marketplace apps.
      

5. Choose the version you plan to upgrade to then hit Check.
   
   

   If you have incompatible add-ons...

   If your users rely on particular Marketplace apps, you may want to wait until they are compatible before upgrading Confluence. Vendors generally update their apps very soon after a major release.

   Good to know:

   • You can disable an app temporarily while you upgrade if it is not yet compatible.
   • Compatibility information for Atlassian Labs and other free apps is often not available immediatley after a new release. In many cases the app will still work, so give it a try in a test site before upgrading your production site.

3. Upgrade Confluence in a test environment

1. Create a staging copy of your current production environment. 
   See Create a staging environment for upgrading Confluence for help creating an environment to test your upgrade in.
     

2. Follow the steps below to upgrade your test environment.  
     

3. Test any unsupported user-installed apps, customizations (such as custom theme or layouts) and proxy configuration (if possible) before upgrading your production environment.   

Upgrade Confluence

4. Back up 

1. Back up your database and confirm the backup was created properly. 
   If your database does not support online backups you'll need to stop Confluence first. 
    
   Once you've confirmed your database backup was successful, you can choose to disable the automatic generation of an upgrade recovery file, as this process can take a long time for sites that are medium sized or larger.
     

2. Back up your installation directory and home directory. 
     

   Where is my home directory?

   You can find the location of your home directory in the <installation-directory>/confluence/WEB-INF/classes/confluence-init.properties file.

   This is where your search indexes and attachments are stored. If you store attachments outside the Confluence Home directory, you should also backup your attachments directory. 

5. Download Confluence

Download the appropriate file for your operating system - https://www.atlassian.com/software/confluence/download

6. Extract the file and upgrade Confluence

1. Stop Confluence.
   See Using read-only mode for site maintenance if you need to provide uninterrupted access.
     
2. Extract (unzip) the files to a directory (this is your new installation directory, and must be different to your existing installation directory)
   Note: There are some known issues with unzipping the archive on Windows. We recommend using 7Zip or Winzip.
     

3. Edit  <Installation-Directory>\confluence\WEB-INF\classes\confluence-init.properties file to point to your existing Confluence home directory.
     

4. If you're using an Oracle or MySQL database, you'll need to copy your jdbc driver jar file from your existing Confluence installation directory to confluence/WEB-INF/lib in your new installation directory. 
     

5. There are some additional steps you make need to take if:
   

   • you are running Confluence as a Windows Service

     Click here to expand...

     If you are running Confluence as a Windows service, go to the command prompt and type:  

     <Installation-Directory>\bin\service.bat remove Confluence

     It is vital that you stop and remove the existing service prior to uninstalling the old instance of Confluence. For more information on running Confluence as Windows service, please refer to Start Confluence Automatically on Windows as a Service.

      To remove the service installed by the Confluence installer, you'll need to run <confluence auto installer installation folder>\UninstallService.bat.

   • You are running Confluence on a different port (not the default 8090) 

     Click here to expand...

     If you are not running Confluence on port 8090 update  <Installation-Directory>\conf\server.xml file to include your ports.

6. Start your new Confluence. You should not see the setup wizard.  

After the upgrade

7. Reinstall the service (Windows only)

If you run Confluence as a service on Windows you should delete the existing service then re-install the service by running <install-directory>/bin/service.bat.

This makes sure the service gets the most recent JVM options. 

8. Re-apply any modifications

If you have customized Confluence (such as an SSL configuration in the server.xml file, or CATALINA_OPTS or JAVA_OPTS parameters in your confluence-init.properties file), you'll need to perform the following steps after the upgrade is complete:

1. Stop your upgraded Confluence instance.
2. Reapply the customizations to the relevant files in the newly upgraded Confluence Installation directory.
3. Restart the upgraded Confluence instance.

We strongly recommend you test your customizations in a test instance prior to upgrading your production instance as changes may have been made to Confluence that make your customizations unsuable.

9. Update your reverse proxy and check you can access Confluence
