You can connect to different servers right from the Server Explorer window in Lean Client. Go to the Server Explorer window and click on the Connect to Server icon.
A prompt will appear that will confirm if you want to disconnect from the current Server and establish connection to a different server. Click Yes to proceed.
Note: A client cannot be connected to multiple servers at once.
You will be directed to the Server Connection screen. Enter the required server information (Server URI and Port Number) to connect to the server and click Connect.
If the connection is successfully established, you should be able to see the connected server in the Server Explorer window.
