If you want to revert from v11.4.1 to an earlier version of WSM, you must uninstall WSM v11.4.1. When you uninstall, choose Yes when the uninstaller asks if you want to delete server configuration and data files. After the server configuration and data files are deleted, you must restore the data and server configuration files you backed up before you upgraded to WSM v11.4.1.

Verify that all WatchGuard servers are running.
