Confluence versions cheatsheet

[#1]

When answering questions here on Community, you may run across questions where you need to provide version-related advice. This guide will help you quickly find which versions you might need to suggest!

Migrations

Confluence Cloud Migration Assistant: 5.10 and up

Single-node Data Center conversion*: 7.2 and up

*you can convert to a Data Center install simply by applying a Data Center license. You no longer have to create a cluster configuration for a single node, making the Server → Data Center migration super easy

Confluence Server and Data Center feature comparison highlights which features are specific to Data Center, and in which version they were introduced.

Supported Platforms

The databases (including database drivers), browsers, importers, and more can vary from version to version.

• Supported platform changes shows a matrix of major changes between Confluence versions for versions back to Confluence 7.0.

• The specific “Supported platforms” pages for each version specify exactly which platforms are supported for that particular version of Confluence. These are linked on the right column of the Supported platform changes matrix. For versions older than 7.0, first open a specific Supported Platforms page, and then use the version picker in the top right to select the version you’re interested in.
  

Bundled Versions

Occasionally questions come up about Java or Tomcat versions. While Atlassian does not support running Confluence in a different Tomcat server than the bundled one, it is possible to use a different Java Runtime Environment than the one included with the Confluence installer.

Adopt OpenJDK has been the included JRE distributor since Confluence 6.14 - Atlassian no longer distributes the Oracle JRE.

• Bundled Tomcat and Java versions

Long Term Support

If you plan to stay on a particular version of Confluence for more than a few months, Long Term Support (LTS) releases are the smart choice. Critical security and bug fixes are backported for the duration of the release’s two-year support cycle.

• Current Long Term Support releases

Other releases can receive support, but not necessarily backported fixes for their two-year lifespan.

• Support End of Life dates

Major features
