Weblogic Server supports a nice feature called side-by-side deployment (or versioned deployment). This function is extremely usefull when you need to deploy a new version of an application and still keep the old one up and running. So the running instances will still use the current version and all new instances will be able to invoke the new deployed version of the application.
As soon as all the sessions who’re using the old version of the application are expired, Weblogic will recognize it and will deactivate the old version. So at this moment only the new deployed version is active and all new sessions will make us of it.
