If you're getting an error 404 after upgrading, you might need to update your license file before starting the application. For example, if you upgrade on SuSE Linux from version 3.0.9 to a revision of version 4.0, you might not be able to log in to continue the upgrade using the admin console.
After upgrading the software, stop the application with appstop, then replace the Jive license file with the one you received for use with the new version. On Linux, you'll find the file at /usr/local/jive/applications/<appname>/home/jive.license
After replacing the file, start the application as described in appstart Command.
