Known issues
- There is a known issue where upgrading Confluence on Microsoft SQL Server fails with an 'invalid column name' error. See CONFSERVER-66547 for a workaround.
- There are a number of known issues when upgrading Confluence on specific database versions. See Confluence 7.11 upgrade notes if you are upgrading from Confluence 7.10 or earlier.
There's a known issue running PostgreSQL on Azure with the bundled version of the driver (42.2.16). See CONFSERVER-60515 for a workaround
If you are upgrading from Confluence 6.3 or earlier, there's a known issue where spaces do not appear in the space directory. You'll need to reindex your site after upgrading to fix this.
- If you use Apache to limit who can access the admin console, you should update your configuration. See Using Apache to limit access to the Confluence administration interface for our suggested configuration.
- There is a known issue where read-only mode attempts to write to
<shared-home>/confluence.cfg.xml, but the file doesn't exist in the shared home directory. This problem affects sites that have been previously upgraded from Confluence 6.0 or earlier. See Could not save access.mode into the shared confluence.cfg.xml file error after upgrading to Confluence Data Center 6.10 - There is a known issue where some fonts that Confluence relies on are not available in older Linux distributions. See Confluence UI shows garbled or corrupt text on CAPTCHA, macros, and/or diagrams due to missing fonts
If you encounter a problem during the upgrade and can't solve it, please create a support ticket and one of our support engineers will help you.
Upgrade procedure
Always test the upgrade in a test environment before upgrading in production.
To upgrade Confluence to the latest version:
- Go to Administration menu
, then General Configuration. > Plan your upgrade and select the version you want to upgrade to. This will run the pre-upgrade checks. - Go to Administration menu , then General Configuration. > Troubleshooting and support tools to check your license validity, application server, database setup, and more.
- If your version of Confluence is more than one version behind, read the release notes and upgrade guides for all releases between your version and the latest version.
- Back up your installation directory, home directory, and database.
- Download the latest version of Confluence.
- Follow the instructions in the Upgrade Guide.
Update configuration files after upgrading
The contents of configuration files such as server.xml, web.xml , setenv.bat / setenv.sh, and confluence-init.properties change from time to time.
When upgrading, we recommend manually reapplying any additions to these files (such as proxy configuration, datasource, JVM parameters) rather than simply overwriting the file with the file from your previous installation; otherwise you will miss out on any improvements we have made.
