Confluence 4.1 Upgrade Notes
Below are some important notes on upgrading to Confluence 4.1. For details of the new features and improvements in this release, please read the Confluence 4.1 Release Notes.
On this page:
Confluence Clustered reactivated
Please be aware that Confluence Clustered is now available again, following a brief hiatus after the release of Confluence 4.0.
Personal labels deprecated
Where CONFLUENCE-URL is the URL of your Confluence site.
Legacy Crowd SSO Authenticator removed
For customers with Crowd SSO authentication who ever used Confluence 3.4.9 or earlier: Customers who were using the
com.atlassian.crowd.integration.seraph.v22.CrowdAuthenticator in their
seraph-config.xml must replace this with
com.atlassian.confluence.user.ConfluenceCrowdSSOAuthenticator. This has been the default Crowd SSO authenticator since Confluence 3.5, so users who installed from scratch with Confluence 3.5 or higher are not affected.
Reduced functionality for JIRA Portlets macro
Upgrade notes updated in March 2012: In Confluence 4.1, it is no longer possible to add avia the Confluence macro browser. It is still possible to add the macro using wiki markup or by copying an existing JIRA Portlet macro. The macro still displays information correctly.
Plain text emails no longer available
Emails are now only available in HTML format, which allows for the display of images and formatted content, such as changes made and the full content of the updated page or blog post.
If you are already running a version of Confluence, please follow these instructions to upgrade to the latest version:
- Before you upgrade, we strongly recommend that you back up your Confluence Home and other important directories and database. See the documentation on backing up your Confluence site. If you are using an external database, perform a database backup.
- If your version of Confluence is earlier than 3.5.x, then you should upgrade to Confluence 3.5.x before upgrading to Confluence 4.1. There are several reasons for this:
- There were major changes to user management and LDAP in Confluence 3.5.
- From version 3.5, you'll be able to use our new automated Installer / Upgrader to move to 4.1. The Confluence 4.1 Installer does not support upgrading from earlier versions of Confluence than 3.5.x.
- We recommend that any issues arising from the upgrade to version 3.5.x be fixed separately to those that may arise from upgrading to version 4.1. Please contact Atlassian Support for assistance.
- Please read the Upgrade Notes Overview and the Upgrade Notes for each version of Confluence listed on that page. (There are hyperlinks to each one.)
If you are upgrading from 2.2 or earlier, you will need to upgrade to Confluence 2.7.x first, confirm the upgrade was successful, then upgrade from version 2.7.x to version 3.5.x, before upgrading to the latest version. For more details, please refer to CONF-11767.
If your site contains links to a file system (for example [\\\C:\Foo\Bar\foobarpreso.ppt] these may break when upgrading to Confluence 4.2.x. We recommend that you upgrade directly to Confluence 5.0.3. Refer to CONF-23575 - Links to filesystem are lost after upgrade to Confluence 4.x or upon saving the page in the new editor Resolved for more details.
- Download the latest version of Confluence.
- Follow the instructions in the Upgrade Guide.
