Upgrading to 7.18.1
Due to changes required for - CONFSERVER-78179Getting issue details... STATUS in Confluence 7.18.1, you won't be able to perform a rolling upgrade to this version. Downtime will be required.
You must wait for node 1 to start completely after upgrading before you attempt to start the next node, or Confluence will fail to start with an 'Unexpected bytes from remote node' error. If this happens, restart your first node.
It is always good practice to wait for a node to start up completely before starting the next node.
New content API
We have added a new REST API endpoint,
rest/content/scan. The new endpoint provides better performance than
rest/content, and adds a cursor parameter which can be used for pagination. It can only be used to browse pages (not blogs), and doesn't support
title , or
See how you can use the API to browse Confluence content

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.
Always test the upgrade in a test environment before upgrading in production.
To upgrade Confluence to the latest version:
- Go to > Plan your upgrade and select the version you want to upgrade to. This will run the > General Configurationpre-upgrade checks.
- Go to > Troubleshooting and support tools > General Configuration 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 ,
confluenceinit.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.
