I had to run some tests on a WebCenter Portal application deployed in a cluster. I've got a development VM with WebCenter PS4 (this also works on PS5) and I was trying to figure out how could I easily add a new managed server to my single-node domain, and make it a cluster. Creating the machine and cluster are a piece of cake, you can do it pretty quick through WLS Console. Now, you'd guess that using the clone option on WLS Console would do the magic of cloning an existing instance, right? Well, it does, but all you get is an "empty" managed server: with no target libraries. 

It was a good surprise to find that WebCenter provides a way of cloning an existing WebCenter Portal managed server through a simple WLST command: cloneWebCenterManagedServer

 This is a screenshot of my starting point. I want to clone WC_CustomPortal managed server:

These are the steps to clone my WC_CustomPortal managed server:

1. In the command line, invoke WLST. It should be on <ORACLE_HOME_for_component>/common/bin/wlst.sh. In my case, it is ./product/Middleware/WebCenterPortal/common/bin/wlst.sh

2. Connect to the Admin Server:  connect ('<wls_admin_username>','<password>','t3://<server>:<port>')

3. Execute the following command:

wls:/webcenter/serverConfig> cloneWebCenterManagedServer(baseManagedServer='WC_CustomPortal', newManagedServer='WC_CustomPortal2', newManagedServerPort=8893, verbose=1)

I've turned on verbose output on purpose so I could see what the script was doing while executing. This is the output:
