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
Jira Cloud Migration Assistant: 7.6 and up
Single-node Data Center conversion*: 8.8 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
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 Jira versions
-
The specific “Supported platforms” pages for each version specify exactly which platforms are supported for that particular version of Jira. These are linked on the right column of the Supported platform changes matrix.
Bundled Versions
Occasionally questions come up about Java or Tomcat versions. While Atlassian does not support running Jira 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 Jira installer.
Adopt OpenJDK has been the included JRE distributor since Jira 8.3 - Atlassian no longer distributes the Oracle JRE.
Long Term Support
If you plan to stay on a particular version of Jira 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.
Other releases can receive support, but not necessarily backported fixes for their two-year lifespan.
