Cloning the stack is simple.

1. Define a new TCP/IP stack configuration disk, e.g. TCPMAINT 298. Populate it by copying over the contents of 198. If you want, you can create a different admin ID such as TCPMNT2.
2. Define a new TCP/IP client disk, e.g. TCPMAINT 692. Populate it by copying over the contents of 592.
3. Clone the stack and desired application server CP directory entries, changing the LINKs to reference 298 and 692 instead of 198 and 592. Leave the 591 disk alone. The servers will need their own 191 disks.
4. Copy TCPROFIL EXEC from the 591 to the 191 as PROFILE EXEC for each server.
5. PROFILE TCPIP on 298 must be updated so that the OBEY, AUTOLOG, INFORM, PERMIT (if applicable), and PORT statements reference the new application servers and sysadmin user IDs. Change the DEVICE, LINK, HOME, and GATEWAY statements as required.
6. SYSTEM DTCPARMS on 298 should contain the :type.server definitions for the new stack's user ID and its application servers. For example:

   :nick.TCPIP2    :type.server  :class.stack
                   :attach.
    
   :nick.MPROUTE2  :type.server  :class.rip
                   :parms.-h
    
   :nick.FTPSERV2  :type.server :class.ftp   :anonymous.NO
    
   .* etc.
