About Long Term Support releases

Supported Platforms

When upgrading from an older Confluence version, where there is no crossover between supported platforms, you may need to upgrade via an intermediary version that supports both your current platform version and future one. For example, if you're running Confluence 5.4 with Oracle 11g and want to upgrade to Confluence 6.x which only supports Oracle 12c, you will need to upgrade via Confluence 5.7 where both Oracle 11g and 12c are supported:

  1. Upgrade to Confluence to 5.7
  2. Upgrade Oracle to 12c and check things run smoothly
  3. Upgrade to Confluence to 6.x

Upgrade Notes

Collaborative editing with proxies and/or SSL

Collaborative editing is powered by Synchrony which synchronizes data in real time. Synchrony is executed as a separate process by Confluence Server and managed by Confluence automatically. Under normal circumstances, it should not need to be managed manually by an administrator.

You may, however need to make changes to your proxy configuration. We made significant improvements in Confluence 6.1, so recommend upgrading to that version or later if you plan to use collaborative editing. 

Upgrading to Confluence 6.0...

If you're ready to implement Collaborative editing, we recommend jumping to 6.1.0 or above. We've made significant changes in 6.1 to make it easier to configure Synchrony with proxies and/or SSL.

If you do plan to upgrade to 6.0.x:

Upgrading to Confluence 6.1 or later...

Have a look at Proxy and SSL considerations to find out whether you need to make any changes to your reverse proxy or SSL configuration. There are a number of configurations to choose from, but only some will require a change to your proxy configuration.

If you experience problems, see Troubleshooting Collaborative Editing.
