Once you deploy the new version you must restart the servers so they can pick up the changes. The best way is to restart the test server and see if everything is ok there. If nothing breaks then restart the other servers. The Fermi experiment has an application called Server Monitoring which gives a list of all servers and a way to start or stop the server. Use the show details link to see what version of java is on the server. Glastlnx08 is the test server so restart it first.
For other experiments that do not have this application, you must log on to each server and restart it manually.
