The Application Upgrade Check in the Universal Plugin Manager (UPM) helps you to check whether your plugins will still work with Confluence after a Confluence upgrade.

For example, if you were thinking of upgrading from Confluence 3.1 to Confluence 3.2, the Application Upgrade Check can tell you the following:

• Installed plugins that are compatible with Confluence 3.1 and Confluence 3.2.

• Installed plugins that are not compatible with Confluence 3.2, even if you upgrade them to their latest version.
