The following procedure allows you to switch to the legacy Integration Server Administrator temporarily. To switch back to the new or default Integration Server Administrator, click Try the New Administration Console. However, if you want to use the legacy Integration Server Administrator every time you start the Integration Server, set the value of the watt.server.defaultPackage parameter to WmRoot, and restart the server. By default, this parameter is set to WmAdmin, which opens the new or default Integration Server Administrator.
