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:

To check if software maintenance is current for your license, go to > Troubleshooting and support tools > General Configuration and make sure the license support period has not expired.
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.

|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.

We use Upgrade Notes to communicate changes that will impact you, such as:
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
Use the table below to determine the most efficient upgrade path from your current version to the latest versions of Confluence.
Recommended upgrade path to Confluence 6
|2.7 or earlier||Upgrade to 2.7.4 then upgrade to 3.5.17, and follow paths below.|
|2.8 to 3.4||Upgrade to 3.5.17, and follow paths below.|
Upgrade to 5.0.3 then upgrade to the latest version of Confluence 6.
4.0 to 4.3
Upgrade to 5.10.x then upgrade to the latest version of Confluence 6.
5.0 to 6.x
Upgrade directly to the latest version of Confluence 6.
Confluence 6 is a major upgrade
Be sure to read the Confluence 6.0 Upgrade Notes, take a full backup, and test your upgrade in a non-production environment before upgrading your production site.
2. Complete the pre-upgrade checks
Check the Upgrade Notes for the version you plan to upgrade to (and any in between).
Go to > Troubleshooting and support tools > General Configuration to run the health check (available in Confluence 5.5 or later).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 > License Details and follow the prompts to renew your license. > General ConfigurationStill using the embedded database?Database character encoding incorrect?
Database character encoding must be set to UTF+8 (or AL32UTF8 for Oracle databases). You will not be able to upgrade to current Confluence versions unless you have the correct character encoding.
Go to and scroll down to the Confluence Update Check to check the compatibility of your add-ons. > Add-ons
Choose the version you plan to upgrade to then hit Check.If you have incompatible add-ons...
If your users rely on particular add-ons, you may want to wait until they are compatible before upgrading Confluence. Add-on vendors generally update their add-ons very soon after a major release.
Good to know:
- You can disable an add-on temporarily while you upgrade if it is not yet compatible.
- Compatibility information for Atlassian Labs and other free add-ons is often not available immediatley after a new release. In many cases the add-on will still work, so give it a try in a test site before upgrading your production site.
3. Upgrade Confluence in a test environment
- 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.
Follow the steps below to upgrade your test environment.
Test any unsupported add-ons, customizations (such as custom theme or layouts) and proxy configuration (if possible) before upgrading your production environment.
4. Back up
- 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.
Back up your installation directory and home directory.
Where is my home directory?
You can find the location of your home directory in the
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
- Stop Confluence.
- 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.
<Installation-Directory>\confluence\WEB-INF\classes\confluence-init.propertiesfile to point to your existing Confluence home directory.
- 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/libin your new installation directory.
- There are some additional steps you make need to take if:
you are running Confluence as a Windows ServiceClick 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 use a Jira application or LDAP for user managementClick here to expand...
If you use Jira or LDAP for user management, copy the following files from your existing installation directory to your new installation directory:
you use Crowd for user managementClick here to expand...
If you are using Crowd for user management, copy the following files from your existing installation directory to your new installation directory:
<Installation-Directory>/confluence/WEB-INF/classes/atlassian-user.xml(if you are upgrading from Confluence 2.2 or later).
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.xmlfile to include your ports.
- 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
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 C
JAVA_OPTS parameters in your
confluence-init.properties file), you'll need to perform the following steps after the upgrade is complete:
- Stop your upgraded Confluence instance.
- Reapply the customizations to the relevant files in the newly upgraded Confluence Installation directory.
- 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
Once your upgrade is complete, you should access Confluence (via your reverse proxy, not directly) and:
- Head to > Collaborative editing and check the Synchrony status is running. > General Configuration
- Edit any page to check that your browser can connect to Synchrony.
See Troubleshooting Collaborative Editing for suggested next steps if Synchrony is not running or you see an error in the editor, as you may have a misconfigured reverse proxy.
Did something go wrong?
If you need to retry the upgrade, you must restore your pre-upgrade backups first. Do not attempt to run an upgrade again, or start the older version of Confluence again after an upgrade has failed.
- Can't proceed with upgrade because license has expired
If your license has expired and was not renewed and reapplied before upgrading you will receive errors during the upgrade process. See upgrading beyond current license period for information on how to resolve this problem.
- Collaborative editing errors
If Synchrony is not running or you see an error, head to Troubleshooting Collaborative Editing for info on how to get collaborative editing up and running in your environment. The most common problems are a misconfigured reverse proxy or port 8091 not being available for Synchrony.
