The Application Upgrade Check in the Universal Plugin Manager (UPM) helps you to check whether your plugins will still work with your application after an application 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, but will be compatible with Confluence 3.2 if you upgrade them.
• Installed plugins that are not compatible with Confluence 3.2, even if you upgrade them to the latest version.

To check compatibility of your plugins against different application versions, navigate to the Plugins page and do the following:
