Autostart Server Clones

Hi everyone. I have a number of quesitons and will appreciate it if I can have some guidance on this matter: What is the best approach regarding configuration of EMC Autostart when cloning server nodes? The plan is to rename the two nodes and will have entirely different host names, alias and IP address.

The second question is can we use the same license on the new servers? especially that after running the cloned servers, the old servers will be switched off.

Thanks in advance for the help.
