To successfully update your version 1.0.1 cluster, you should update in the following order:
Update the Lucene Servers first.
Update each Filr appliance separately. Do not attempt to update more than one appliance at a time.
If required, the MySQL database is automatically updated when the first Filr appliance is updated.
As each Filr appliance is updated, log in directly to the appliance (not through a proxy).
If you do not see normal operations, use port 9443 and check the following log files for errors or other abnormal operations: ssf.log, ssr.log, and catalina.log.
